Mitosis is a process used for normal growth and development. Explain how and why a mutation in a BRCA gene may affect the cell c
Romashka [77]

Answer:

The BRCA gene is a tumor-suppressor gene found in the breast; to be more specific, it produces proteins that suppress cancerous activities/abnormal growth in the body. A mutation in a BRCA gene would allow these abnormal growth activities to go unchecked and thus increase the rate of mitosis. Cell cycle checkpoints would significantly be worse at their jobs of checking and correcting for errors during the cell cycle. Tumors would result as well, as cancerous growth continues, and the tumor can become metastatic.

Family
Genus
Species

The largest level would be the one closest to the top of the list because it is the least specific and therefore the most inclusive. Out of the choices given, phylum is closest to the top, so that is the answer.
