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?

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.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
