Final answer:
Tumor suppressor genes are genes that normally slow down or stop cell division. When a mutation occurs in a tumor suppressor gene, it can lead to uncontrolled cell growth and cancer. An example of a recessive (tumor suppressor) loss-of-function mutation is the BRCA1 gene mutation.
Step-by-step explanation:
Tumor suppressor genes are genes that normally slow down or stop cell division. When a mutation occurs in a tumor suppressor gene, it can no longer control cell division.
This can lead to uncontrolled cell growth and the development of cancer.
An example of a recessive (tumor suppressor) loss-of-function mutation is the BRCA1 gene mutation, which is associated with an increased risk of breast and ovarian cancers.
