Question

Indicate whether each of the following descriptions applies to an oncogene, a proto-oncogene, or a tumor suppressor gene. Some descriptions may apply to more than one of these gene types.

Type of gene(s) found in cancer cells.

- type of gene(s) found in normal cells and cancer cells.
- gene(s) that could code for a normal growth factor.
- gene(s) whose absence can cause cancer.
- type of gene(s) found in normal cells.
- gene(s) whose presence can cause cancer.
- type of gene(s) found only in cancer cells.

Answer 1

Step-by-step explanation:

Type of gene(s) found in cancer cells -------------- oncogene

type of gene(s) found in normal cells and cancer cells ----- oncogene, proto-oncogene

gene(s) that could code for a normal growth factor ---------------- proto-oncogene

gene(s) whose absence can cause cancer --------- tumor suppressor gene (anti-oncogene)

type of gene(s) found in normal cells ----------- oncogene and proto-oncogene

gene(s) whose presence can cause cancer ------------- oncogene

type of gene(s) found only in cancer cells ------- oncogene

Oncogene are the switch off of proto-oncogene and are responsible for abnormal cell growth. Oncogene are found in all normal cells. They are mutated proto-oncogene.
