Question

11. Which one of the following best fits the description of “commitment” in Developmental Biology?

a) Commitment is defined as the process cells use to take on their mature gene expression patterns which alters the shape of a cell and/or tissue structures to match a particular function for that cell or tissue.

b) Commitment is the process whereby a single proliferating cell is prevented from undergoing additional rounds of cell division during its life span and the process is independent of the type of organ or tissue of which the cell is a component part.

c) Commitment occurs when one cell converts its “fate” from one lineage to another by turning on a completely different set of genes than were previously expressed.

d) Commitment is the switch from a proliferating to a post-mitotic cell.

Answer 1

Ans Cell commitment is define as regulation of cell to its particular cell fate differentiate to carry out its function. The cell undergo change in biochemistry and function to get committed toward particular cell fate. the commitment is dependent upon the cell fate

a ) commitment is define as the process cells use to take on their mature gene expression pattern which alters the shape of a cell and/or tissue structure to match particular function for that cell or tissue
