Question

A particular dna sequence reads tcgaggtcaccg. a mutation occurs in which the first "a" in the sequence is deleted. what will happen to the protein produced?
a. the first amino acid will be wrong, but the last three will be correct.
b. the first two amino acids will be wrong, but the third and fourth amino acids will be correct.
c. the first amino acid will be correct, but every amino acid after that will be wrong.
d. the first, third, and fourth amino acids will be correct, but the second amino acid will be wrong.

Answer 1

Amino acids are "read" in groups of three. If the first "a" is deleted, the first amino acid from "tcg" will be correct, but every amino acid after that will be wrong. The second amino acid, for example, would be "ggt" instead of "agg".
