Solution :
The central dogma of the molecular biology is described as
DNA → RNA → Protein
Now the arrow between the RNA and the DNA cannot be reversible because practically it does not happen. When the RNA polymerase the enzyme binds to the DNA strand, and the mRNA is made up and whether the protein is for beneficial or not, the mRNA cannot move back to the DNA. Therefore, it cannot be reversible.
For protein name should be made plural
At time, The DNA is transcribed to the mRNA and also one mRNA is transferred to the single protein. If there are more than one protein, then they would be coming from the different mRNAs.
The definition of the central dogma ends at the protein. There is no circular process as the different genes can be transcribed and also translated to the different proteins.
What is the difference between genetic and chromosomal mutations
Answer:
Gene mutation may alter the function of proteins in the body. Chromosomal mutations can be either an alteration of chromosome structure or chromosome number. ... The main difference between gene mutation and chromosomal mutation is the magnitude of alterations that occur in the genetic material by each type of mutation.

Plss help me with this carbon cycle!!!!
Answer:
Plants photosynthesize, so they need, thus absorbs carbon dioxide. Marine plants also need carbon dioxide for photosynthesis so they absorb. Dead plant and animal matter decay to release carbon dioxide as a result.
A carbon footprint refers to the greenhouse gas emissions caused both directly, and indirectly, by an individual, a product, an organization, or an event.

Carbon dioxide is a compound with one carbon atom and two oxygen atoms. About 0.04% of the Earth's atmosphere is carbon
dioxide. Carbon dioxide absorbs heat radiated from the Earth's surface.
Which of the following statement is true?
ОА.
Carbon absorbs most of the heat radiated from the Earth's surface.
OB. Carbon and oxygen have properties that are identical to those of carbon dioxide.
OC.
Carbon and oxygen have properties that are different from those of carbon dioxide.
OD

Answer:
OC
Explanation:
That is just because carbon and oxygen on their own are different as oxygen has more mass or weight than carbon and besides it is 2 oxygens and a carbon that will give you carbon dioxide.
Can a gene mutation that does not influence phenotype be considered an adaptation? Why or why not?
Answer:
No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

what is meant by aseptate coenocytes
Answer:Filamentous fungi may contain multiple nuclei in a coenocytic mycelium. A coenocyte functions as a single coordinated unit composed of multiple cells linked structurally and functionally, i.e. through gap junctions. Fungal mycelia in which hyphae lack septa are known as "aseptate" or "coenocytic".
Coenocytic cells are present in diverse and unrelated groups of algae, including Xanthophyceae, red algae and green algae.
In the siphonous green algae Bryopsidales and some Dasycladales the entire thallus is a single multinucleate cell, which can be many meters across. However, in some cases, crosswalls may occur during reproduction.
Explanation:The green algal order Cladophorales is characterized by siphonocladous organization, i.e., the thalli are composed of many coenocytic cells.
In contrast to the Cladophorales where nuclei are organized in regularly spaced cytoplasmic domains, the cytoplasm of Bryopsidales exhibits streaming, enabling transportation of organelles, transcripts and nutrients across the plant.

What factors play a role in how fast, far, or what direction DNA fragments travel for gel electrophoresis?
Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode, Shorter strands of DNA move more quickly through the gel than longer strands resulting the fragments being arranged in order of size.

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.
Please help!
Answer:
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Explanation:
1) First, transcribe the DNA to RNA. For each nitrogenous base (to put it simply, the letter) listed in the DNA strand, write the strand of RNA with the matching nitrogenous base. Remember that, when transcribing, the thymine (T) from DNA can pair with adenine (A) in the RNA, adenine (A) pairs with uracil (U), and cytosine (C) and guanine (G) always pair with another.
DNA: [tex]T-A-C-A-T-A-T-G-C-C-T-A-A-C-T[/tex]
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
2) Next, to find the amino acids the strand codes for, read the nitrogenous bases in the RNA from left to right in groups of three, or codons. Then, using a codon chart, find which amino acid the group of three bases codes for. This gives the following answer below. (Remember that the codon UGA stops the translation and therefore does not code for an amino acid.)
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
What are amino acids?Amino acids are the building blocks of protein. Proteins are long chains of amino acids. Your body has thousands of different proteins that each have important jobs. Each protein has its own sequence of amino acids.
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids.
The human body uses amino acids to make proteins to help the body: Break down food. Grow. Repair body tissue.

For several years,researchers have atempted to produce AB artificial blood for transfusions. Artificial blood would most likely to be safer and more readily available than human blood.while the artificial blood might not have all the characteristic of a human blood, it would be useful on the battlefield and in emergency situations. which characteristics of normal blood must artificial blood have to be useful and which would probably be too difficult to produce .
Answer:
It is a good concept but can't be used.
Explanation:
Producing artificial blood is a good concept but it can't take the place of real human blood because the artificial blood has many disadvantages which can cause great damage to our body such as binds nitric acid that affected blood flow, increases the level of bilirubin, amylase and lipase in the blood and also cause overload of iron in your organs or tissues so that's why it can't be used instead of original human blood but may be in the future if these complications are removed.
How do the vrg and drg control and regulate the respiratory rate?
Answer:
The ventral respiratory group (VRG) and the dorsal respiratory group (DRG) within the medullary rhythmicity area cooperate to establish the pattern for spontaneous ventilation and basal rate of ventilation which may be adjusted by impulses from related respiratory control centers in the pons; the ventral respiratory group (VRG) contains both inspiratory and expiratory neurons; the autorythmic inspiratory neurons stimulate the diaphragm and external intercostals for approximately 2 seconds to cause inspirations and then the antagonistic expiratory neurons fire for approximately 3 seconds to permit passive or stimulate active expirations; thereby inspiratory and expiratory neurons cooperate in a negative feedback control relationship, setting the basic rhythm of respiration (spontaneous ventilation, resting or tidal breathing (eupnea)); the dorsal respiratory group (DRG) neurons are involved in altering the pattern for ventilation in response to the physiological needs of the body for O2 and CO2 exchange and for blood acid-base balance; these neurons stimulate neurons in the ventral respiratory group (VRG) to achieve those effects; they are responsive to sensory information from chemoreceptors and mechanoreceptors.

Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected simultaneously with phage strains rII1 and rII2 at a high moi. The progeny phage are collected and used to infect cells of E. coli K. This infection is also carried out at a high m.o.i., and the resulting phage are collected. These progeny are diluted and plated on both E. coli B and E. coli K. Do you expect more plaques on strain B, on strain K, an equal amount on both or is it impossible to tell?
A. E. coli B
B. E. coli K
C. Equal on both
D. Can't tell
Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect E. coli cells and the numbers of these E. coli cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that E. coli strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on E. coli K strains that carry phage λ (lysogenic for λ), but they produce plaques on E. coli B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
Why is ATP like a charger battery and ADP is like an uncharged battery ?
Answer:
When a cell has no available energy, it is able to store energy by adding a phosphate group to an ADP (adenosine diphosphate) molecule. The ATP molecule that results is like a battery because both the molecule and a battery contain stored energy, while, on the other hand, ADP is a partially charged battery.
