Mitosis - Asexual, diploid, 1, 2, during the synthesis phase.
Meiosis- sexual, haploid, 2, 4, during the synthesis phase.
Answer:
The correct answer is beginning of cell mitosis.
Explanation:
Cyclins are cell cycle regulatory protein which regulates the catalytic activity of cyclin dependent protein kinase or CDK.From the name cyclin dependent protein kinase it can be concluded that CDK helps in the phosphorylation of key proteins of cell cycle.
The combination of cyclin with CDK helps in the progression of cell from one phase to another.
Such as cyclin A CDK 2 helps also called G1 cyclin CDK helps in progression of cell from G1 to S phase whereas Cyclin B CDK 1 or M cyclin CDK helps in beginning of mitosis phase or M phase of the regulated cell.
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.
Cells are made of the same DNA but they can have different functions. It depends on where they are in your body; each of them have a separate job. There are different types of cells. Apparently, for a cell to work...1000 proteins must be made.
