Hello all. I really need help immediately with this question. Here is the question! Explain how these terms work together IN TRANSLATION: mRNA, tRNA, codon, amino acid, protein
Thank you sm for the help :)

Answers

Answer:

Translation takes place in 3 main steps: initiation, elongation and termination.

In initiation, the ribosome binds with the mRNA strand and a initiation complex forms. An initiator tRNA molecule brings the first amino acid, methionine. It binds with the start codon using its anticodon, UAC. The large ribosomal subunit then binds to the small ribosomal subunit.

In elongation, more charged tRNAs bring the amino acids to be added on the growing polypeptide chain. Elongation continues until the ribosome encounters the stop codon.

In termination, a release factor binds to the stop codon, causing the polypeptide to be released from the ribosome. The ribosomal subunits separate from the mRNA and from each other. The polypeptide undergoes folding to form secondary and tertiary structures to become a fully-functional protein.

Notes:

• Translation is the process by which a protein is synthesized from mRNA.

• mRNA: messenger RNA

• tRNA: transfer RNA

• codon: A 3-nucleotide sequence that codes for a specific amino acid. For example, AUG codes for methionine.

Select all that are true regarding ATP cycling


A. ATP is formed from ADP and phosphate

B. Energy for ATP synthesis comes from the oxidation of glucose and other fuel molecules

C. ATP hydrolysis is an endergonic reaction

D. Oxidation of ATP can be used for performing endergonic reactions in the cell

Answers

Answer:

A, B and D are correct

Explanation:

Adenosine diphosphate (ADP) can form a bond with a phosphate group to form Adenosine triphosphate (ATP), which is the most abundant energy carrier molecule in cells. An endergonic reaction is a chemical reaction where there is a net input of energy, while an exergonic reaction generates energy. ATP hydrolysis releases energy (conversely to ATP synthesis that requires an input of free energy), and therefore ATP hydrolysis is an exergonic reaction. ATP hydrolysis releases around 7.3 kilocalories per mole. In a coupled reaction, the energy released by ATP hydrolysis is used by the cell to carry out endergonic reactions in an exergonic manner (e.g., glucose phosphorylation, which is an energetically unfavorable reaction).

Why are most genes inhibited in an average animal cell

Answers

Answer:

Most genes must be turned off because cells play specific functions, thereby only a limited number of genes must be expressed in each cell type in order to produce proteins required in the cell  

Explanation:

Gener regulation is a critical molecular mechanism required for normal cell functioning. In consequence, genes are turned on and off depending on the cell type. For example, in the brain, cells that will be differentiated into neurons will be expressed, while genes involved in the differentiation of undifferentiated myoblasts into muscle cells will be turned off. Thus, genes are switched off in order to produce only those specific proteins which are required for each cell during specific developmental programs and functions carried out by each cell type.

O C. Finisher operations raise hogs throughout their lifetime, feeder operations raise young hogs, and farrow-to-finish operations raise older hogs.

O D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs

Answers

Answer:

D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs

Explanation:

Hog farms operate in three different categories:

Farrow-to-finish: This involves breeding sows to produce offspring.  The offspring's are then fed until they are have reached the size for slaughter. The entire process takes throughout the hogs lifetime.

Feeder operations: This involves breeding sows and then selling their piglets to other farmers who will then raise them for till they are matured for slaughters. This process is just to raise young hogs.  

Finisher operations: This involves buying piglets from other farmers and then raising them until they are matured for slaughter. This finisher operations raise older hogs

Answers

Answer:

in fossils we see homologous structures that suggest a common ancestor.

By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.

When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).

Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.

Plants have specialized cells that produce strong odors to attract insects.

Example:- The inflorescence of the titan arum plant attracts specific pollinators by emitting an intense, carrion‑like odor.

Why plants attract insects?Flowering plants attract pollinating insects with scent from their flowers and bright colors.

Group of answer choices


carbohydrates


proteins


lipids


nucleic acid

Answers

Answer:

The correct answer is ''proteins.''

Explanation:

Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.

OB. Fewer people are needed to weed because of herbicides.
O C. Fewer crops are produced because of herbicides.
O D. Fewer crops are organic because of the use of Bt toxin.
O Mark for review (Will be highlighted on the review page)

Answers

Answer:

B. Fewer people are needed to weed because of herbicides.

Explanation:

Herbicides are chemical substances specifically used to control the widespread growth of weeds i.e unwanted plants. Using herbicides has been useful in eradicating the weeds that pose a great threat to agricultural productivity.

Since chemical control (herbicides) has proven to be a faster and effective method, fewer people are needed to involve in the physical control of weeds i.e. weeding. Hence, the use of herbicides has affected agricultural productivity by helping to reduce the amount of laborers.

mechanical weathering looks like the answer

The type of weathering seen in the pictures is mechanical weathering.

Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.

Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.
