Cell differentiation always involves the
A)production of tissue-specific proteins, such as muscle actin.
B)movement of cells.
C)transcription of the myoD gene.
D)selective loss of certain genes from the genome.
E)cell's sensitivity to environmental cues such as light or heat.

Question

Quizplus · Accepted Answer

Cell differentiation involves the production of tissue-specific proteins, such as muscle actin, which are necessary for the cell to perform its specific function in the tissue. Differentiated cells have distinct gene expression patterns that are determined by their respective tissue types.

Note: choices B, C, D, and E are not necessarily incorrect, as they may play a role in certain types of cell differentiation. However, they are not universally applicable to all types of cell differentiation, whereas the production of tissue-specific proteins is a fundamental aspect of all cell differentiation.
