Question

What is apoptosis? A. The proliferation of cytotoxic T-cells. B. The receptor on a cytotoxic T-cell that recognizes MHC molecules. C. The process of programmed cell death. D. A protein molecule that forms a pore in the membranes of infected cells.

Answer 1

Option-C

Step-by-step explanation:

Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.

During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.

Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.

Thus, Option-C is the correct answer.
