a. The first has fewer amino acids than the second.
b. The first has isoleucine where the second has leucine.
c. The first has one more amino acid than the second.
d. The first has serine where the second has valine.

Answer 1

Answer:

The first has one more amino acid than the second.

Explanation:

(Took test)

Answer 2

C option is the right answer which states teat the first has one more amino acid than the second.

Explanation:

The first mRNA sequence codes for the Methionine (start codon), isoleucine, valine, and tyrosine.

The second mRNA sequence for the Methionine, isoleucine, valine only, because the last sequence (UAG) is of stop codon and stop codon do not code for any of the amino acids.
