Chapter 24, Problem 26CONQ

Summary Introduction

To review:

The rare involvement of activated oncogenes in the inheritance of different forms of cancer.

Introduction:

Cancer is a disease caused by an uncontrolled division of cells in the body, mainly due to the occurrence of mutations in the genes. Oncogene in a mutant gene that promotes cancer. A non-mutated gene that has the potential to convert into mutated gene later is termed asproto-oncogene, which later converts into oncogenes and causes cancer. Tumor-suppressor genes, as the name suggests, are those genes that help prevent cancerous cells to proliferate.
