Question

Determine if the statement is true or false, and why. “If a point mutation occurs in a proto-oncogene it can form an oncogene. This can stimulate excessive cell division, leading to the formation of a tumor.”

Answer 1

The above statement is true.

Step-by-step explanation:

A proto-oncogene can be described as a gene which is normal but if mutation occurs then it can be converted into a cancerous gene. Proto oncogenes have different functions to perform. Some of them act as signals for cell division while others might be involved in the process of apoptosis. A point mutation can be described as a mutation by which just a single nucleotide gets changed. Even a change in the single nucleotide can cause a proto oncogene to convert into an oncogene and cause cancer.
