Cancer-causing mutated tumour suppressor genes result from which of the following?
A)programmed cell death
B)mutations in genes encoding proteins that normally inhibit progression through the cell cycle

D)cell-contact inhibition

Question

Quizplus · Accepted Answer

Tumour suppressor genes normally inhibit cell growth and division. Mutations in these genes can cause them to lose their function or become inactive, leading to uncontrolled cell growth and the development of cancer. Mutations in genes encoding proteins that normally inhibit progression through the cell cycle can result in cancer-causing mutated tumour suppressor genes.
