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 most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
