NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: Cell differentiation is the process in which cells become specialized in structure and function. It is the specialization of cells in different directions from a common cell type.

Detailed explanation-2: -Cell differentiation is the process of cells becoming specialized as they body develops. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

Detailed explanation-3: -In order for a cell to differentiate into its specialized form and function, it need only manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.

Detailed explanation-4: -Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.

Detailed explanation-5: -Gene Expression Regulates Cell Differentiation Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression.
