Which of the following statements is not true for cancer cells in relation to mutations

Options

A. Mutations destroy telomerase inhibitor
B. Mutation inactivate the cell control
C. Mutations inhibit production of telomerase
D. Mutations in proto-oncogenes accelerate the cell cycle

Answer

C

Explanation

Telomerase replaces short bits of DNA (telomeres) which are shortened when cell undergoes mitosis. Telomerase enzyme is high in cells which divide repeatedly ,e.g. stem cell. The enzyme is at a very low level or absent in somatic cells. Persistent high telomerase level in the cells will allow them to undergo unbounded growth as is the feature of cancerous cells.
