#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.
