Question

Oncogenes act _____; one copy of the gene _____, regardless of whether or not there is a normal, unactivated copy of the gene on the homologous chromosome.

Answer 1

Oncogenes are genes that, when mutated, become continuously active and stimulate cell division and growth. One copy of an oncogene is enough to cause its effects, regardless of the presence of a normal copy of the gene.

Step-by-step explanation:

Oncogenes are genes that normally help cells divide, but when they mutate to become oncogenes, they become continuously active, even when they are not supposed to be.

These oncogenes can stimulate cell division and growth, leading to uncontrolled cell growth and ultimately cancer. One copy of an oncogene is enough to cause its effects, regardless of whether or not there is a normal, unactivated copy of the gene on the other chromosome.
