Cellular Differentiation is Usually Produced By

Question

Cellular differentiation is usually produced by
A) morphogenesis.
B) differences in DNA sequences.
C) differences in gene expression.
D) differences in gene copy numbers.

Accepted Answer

Cellular differentiation is the process by which cells become specialized in structure and function. This differentiation is controlled by the expression of specific genes. As cells differentiate, certain genes become more or less active, leading to differences in the proteins that are produced and ultimately to differences in cellular structure and function. Therefore, differences in gene expression are the main reason for cellular differentiation.
