The diagram represents the role of genetic material in an organism, with two structures labeled A and B

Why do structures A and B lead to the expression of different characteristics in an individual?

• because they have different sizes

• because they have different DNA sequences

• because they produce the same type of proteins

• because they are present at different locations on a chromosome
