Question

If the sequence ATGCATGTCAATTGA were mutated such that a base were inserted after the first G and the third T were deleted, how many amino acids would be changed in the mutant protein?

Answer 1

Answer:

Two

Explanation:

Consider the sequence ATGACATGCAATTGA.

Originally, there are 5 codons, translating to a minimum of 5 amino acids: ATG CAT GTC AAT TGA.

A base was inserted after the first G and the third T was deleted, the sequence become (assuming A is the inserted base);

ATG ACA TGC AAT TGA

Only the second and the the third codon are changed and hence, their respective amino acid.
