Question

Quizplus · Accepted Answer

Each cell in the body contains the same genetic information (DNA), but the expression of different genes is regulated differently in different cells. This regulation of gene expression allows cells to differentiate and become specialized to perform specific functions. For example, muscle cells express genes for contractile proteins while nerve cells express genes for neurotransmitters.
