If the sequence of an mRNA moving through the ribosome has the sequence 5'AUGCCAGCGGAUCGC3', what is the sequence of the polypeptide produced from translating this segment
Answer:
MPADR (methionine-proline-alanine-aspartic acid-arginine)
Explanation:
Translation is the mechanism for which a protein is synthesized from the information encoded in the messenger RNA (mRNA). The mRNA is a single-stranded molecule that consists of a chain of nucleotides, where three-letter combinations of nucleotides 'or codons' specify the order of the corresponding amino acids in the polypeptide chain. The ribosome reads the mRNA by one codon at a time and thus translates this information into a polypeptide, where each codon is specific for one amino acid. In this code, the start codon is AUG (which is read as Methionine), while stop codons can be UAG, UAA, and UGA.

Why does the amount of energy available change as you move from one
trophic level to the next? Does this process still follow the Law of
Conservation of Energy? Explain your reasoning.
Answer:
hope it helps you
Explanation:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.

Which of the following is true regarding the machinery of translation?
a. A single mRNA can be translated simultaneously by several ribosomes.
b. tRNAs released from the ribosome are degraded B) termination and eukaryotes utilizes three different release factors.
c. Polycistronic MRNA usually has a single ribosome binding site.
e. once a single mRNA strand is translated once it is degraded
Answer:
The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.
Explanation:
Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.
To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a polysome and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.
The true statement regarding the machinery of translation is ; ( A ) A single mRNA can be translated simultaneously by several ribosomes
Translation is the process of producing protein with the use of RNA ( i.e. the process of protein synthesis from an mRNA template ) during translation the code found in the template is converted into an amino acid sequence.
Ribosomes are composed of rRNA which directs the process of translation with the proteins and key molecules such as tRNA.
Hence we can conclude that the true statement regarding the machinery of translation is A single mRNA can be translated simultaneously by several ribosomes.

Which are the two most important factors determining the movement of ions across the cell membrane?
Answer:
The two most important factors determining the movement of ions across the cell membrane are: the permeability of the molecule in the membrane, and the existence of an energy source.
Explanation:
Ions are charged molecules that, no matter their size, cannot pass through the membrane by simple diffusion because of the nature of the lipid bilayer of the membrane.
Ions can move across the cell membrane in two different ways: passive transport and active transport. The disparity between these two relies on the usage of ATP (energy) - passive transport doesn't need ATP while active transport does. This is where the availability of a source of energy is important, because if there isn't, then active transport is impossible.
On the other hand, ions can move through the cell membrane without the use of energy by diffusing through the membrane with the help of specific membrane proteins that form channels for ions to pass through - and this is where permeability matters: if the cell membrane is permeable to a specific ion, it means that it has opened channels for that ion to use; and this ion will move from one fluid to the other (intracellular or extracellular) following its concentration gradient (for example, sodium is poorly concentrated in the inside of the cell, while is highly concentrated on the outside - this means that sodium will go through the membrane to get inside the cell and even the concentrations between the two fluids, but only if the membrane is permeable to sodium!).
Here is what I want you to do. Create a comic strip using one of the following websites. Some of the websites you must pay for, so DON'T PAY for them, just take a screenshot and send it to me in an email.
You can also complete the project using poster board. Either way is fine. Once completed with poster board, you must send it to me by taking a picture through an email.
The key to the assignment is to make sure you will model the structures of the cell and describe their functions. You will do this by completing a table that describes the functions of structures of the cell. The table should also identify factory parts or workers that have similar functions.
The comic strip is just a way to describe the cell structures. It's a scenario (scene) describing the events. The scene is of a reporter who visits a cell “factory” and interviews someone about the structures/organelles and how their roles in the cell are similar to those of a factory and its workers.

How does the formation of NAD+ differ between aerobic and anaerobic respiration?
A. NAD+ is formed in aerobic respiration by a fermentation process and formed in anaerobic respiration by oxidation of NADH.
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.
D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.
Answer:
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
Explanation:
Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.
Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?
Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.

A student places a healthy potted plant and a plastic straw in a closet for two weeks. After two weeks, the student observes that the plant is wilted and brown, while the plastic straw remains the same.
The student classifies the plant as living and the plastic straw as nonliving,
What criteria does the student use to classify the plant as living rather than nonliving?
The plant needs energy from sunlight to make food for survival.
The plant produces pollen for reproduction of its species.
The plant generates sugars that are consumed as food by other organisms.
The plant produces offspring with characteristics similar to the parent plant
Answer:
According to the experiment, the criteria used by the student to classify the plant as living rather than non-living is that plant needs energy from sunlight to make food for survival.
Explanation:
One of the characteristics that defines plants as living is their ability to perform functions proper to living beings, such as nutrition, growth, development and reproduction.
Plants are autotrophic organisms, capable of producing their own nutrients from sunlight, so they require this type of energy for their nutrition and survival.
The fact that the plant that remained in the closet for 2 weeks turned brown and wither demonstrates the need it has for sunlight, which is a valid criteria for considering it a living being, in comparison with the non-living object.
The other options are characteristics of plants as living beings, but they are not the criterion that demonstrates that plants are living beings, in accordance with the proposed scenario.

why do our digestive systems produce separate enzymes to digest proteins, fats, and carbohydrates?
Answer:
The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.
Explanation:
Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.
There are different enzymes, produced in the digestive system, for this purpose:
Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.
Permits in the cap and dividend policy are issued for _______ production. a. carbon dioxide b. timber c. water pollution d. plastic
Answer:
the answer is A.. I think
Permits in the cap and dividend policy are issued for carbon dioxide production. Therefore, option (A) is correct.
What is The cap and dividend policy?The cap and dividend policy is one potential approach to lowering carbon emissions and slowing the progression of climate change. The way it works is by first establishing a limit on the total amount of carbon emissions that are permissible within a given time period, and then handing out permits to businesses in proportion to the amount of emissions that they are responsible for producing.
If a company emits fewer greenhouse gases than their allotted amount, they have the option of selling their unused permits to businesses that have a demand for more. This results in the creation of a revenue stream that can be distributed to individuals in the form of a dividend, as well as a financial incentive for businesses to reduce the amount of carbon emissions they produce.

For keyboard navigation, use the up/down arrow keys to select an answer. a the relative distance between the genes b the presence of more than two alleles at each locus c that genetic material was being exchanged with the Y chromosome d the number of genes that could be found on any given chromosome
Answer:
The correct option is a) the relative distance between the genes.
Explanation:
A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close have a few recombination events and are strongly bounded. These genes are linked.
The percentage of recombination frequency (P = Recombinant number / Total of individuals) is useful to determine the genetic distance between two or more genes. This distance results from multiplying that frequency by 100 and expressing it in map units (MU) or centiMorgans (cM). One centiMorgan (cM) equals one map unit (MU).
The map unit or centiMorgan is the distance between the pair of genes for which every 100 meiotic products only one results in a recombinant product.
