The BRCA1 gene _______.

  1. a. is a checkpoint gene
  2. b. is a proto-oncogene
  3. c. encodes a tumor suppressor
  4. d. all of the above

Summary Introduction

Introduction: BRCA1 are human genes normally expressed in the cells of breast and other tissue. Actually BRCA is an abbreviation for breast cancer gene. This gene normally plays a big role in preventing breast cancer. They help to repair DNA breaks that can lead to cancer and the uncontrolled growth of tumors.

Explanation of Solution

Reason for the correct statement:

BRCA 1 gene is the breast cancer gene which codes for a tumor suppressor protein. Tumor suppressor proteins help repair DNA that has become damaged in order to ensure stability of genetic material in cells. The BRCA 1 protein prevents cells from dividing too rapidly. It functions as a tumor suppressor gene which encodes for resisting the action of the tumor genes. It also acts as a proto-oncogene that becomes an oncogene by any sort of mutation.

Option d. is given as “all of the above”.

BRCA 1 is a gene that can act as a checkpoint gene as well as the gene encoding for tumor suppression. It also functions as a proto-oncogene.  So, option d. is the correct answer.

Reasons for the incorrect statements:

Option a...
