Question

What if the first triplet as CAA?

Answer 1

If the first triplet is CAA the amino acid is glutamine

Step-by-step explanation:

Analyzing the genetic code we can determine that a certain sequence of 3 nucleotides know as a codon will encode a specific amino acid. This can be easily determined with the genetic code table. The genetic code table is a table that summarize all the possible codons and the amino acids that they encode.

if we study the table we can see that the first letter of our codon is C, the second one is A and the third one is A the amino acid that is encoded is glutamine.

Answer 2

I believe; CAA codes for glutamine, therefore, there is a change in the amino acid sequence. It would not be correct to say now this person has a chance of developing diabetes, because A. the first codon of insulin isn't proline and B. the N-terminus of insulin contains a signal peptide, which is removed from the final, active product.
