Question

A new gene is discovered, called SHOSH. It prevents a cell from entering mitosis if there are any signs of DNA damage. This means that SHOSH would be a type of _____ and that _____ mutations in SHOSH would be associated with cancer.

Answer 1

Answer:

tumor suppressor gene, inactivates

Explanation:

A tumor suppressor gene is also known as the anti- oncogene. A tumor suppressor is a gene that regulate cell during cell division and replication. Uncontrollable cell growth will result in CANCER.

Tumor suppressor genes can be divided into caretaker, gatekeeper and landscape genes.

(1). CARE TAKER GENES: makes sure that there is stability of the genome through DNA repair.

(2). GATEKEEPER GENES: gatekeeper genes regulate cell growth by inhibiting cell cycle progression.

(3). LANDSCAPE GENES: Landscape genes regulate growth by contributing to the surrounding environment.

Tumor suppressor gene function as cell cycle coupling, apoptosis, cell adhension and gene repression.

Since the gene PREVENTS A CELL FROM ENTERING MITOSIS if there are any signs of DNA damage, IT IS A TUMOR SUPPRESSING GENE.
