#9 I need help please
kondor19780726 [428]

Answer:

500 amino acids

500 codons

Yes

Explanation:

A codon is a set of 3 base pairs. Each codon codes for a specific amino acid. So the ratio between codon and amino acid is 1:1 and the ratio between base pairs and codon is 3:1.

If you have 1,500 base pairs then we can mathematically solve the number of codons:

\dfrac{1,500}{x} = \dfrac{3}{1}\\\\(1,500)(1) = (3)(x)\\\\\dfrac{1,500}{3} = x\\\\ 500=x

Since the ratio of codon to amino acid is 1:1, then for every 500 codons, there are 500 amino acids.

I hope this helps clear it up a bit for you.

Disulfide bonds are important in determining and stabilizing protein structure. Which amino acid, if mutated, will affect the fo
elixir [45]

Answer:

c. cysteine

Explanation:

Cysteine is a non essential amino acid. It contains sulfur in form of thiol group. A disulfide bond or bridge is formed between two thiol groups. It is represented as S-S. It is formed by oxidation of two cysteine molecules. The resultant disulfide bond is called as cystine which connects two polypeptide chains.

Cysteine is the only amino acid capable of forming disulfide bridge. It stabilizes protein's globular structure and plays an important role in protein folding and stability. Cysteine is required for protein synthesis, metabolic processes and detoxification. It is the part of beta-keratin which is the main protein in nails, hair and skin. If cysteine is mutated, formation of disulfide bond will be affected.
