Answer:
(Choice A)
A
Genes encode molecules that are necessary for cell specialization.
(Choice B)
B
Genes can code for proteins.
Both A and B are correct. Genes are segments of DNA that carry the genetic information necessary for the cell to carry out essential life functions. The genetic code in the genes is transcribed into RNA, which is then translated into proteins. Proteins are essential molecules that carry out a wide range of functions in the cell, such as catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules across cell membranes. They also play a critical role in cell specialization by controlling the differentiation of cells and the formation of tissues and organs.
