What are some factors that might cause a cell to be unable to regulate its cell cycle

Some of the factors that might cause unregulated cell cycle are-

Explanation:

1. Genetic Mutation- mutation in the proto-oncogenes can turn them into oncogenes which stimulate cell division. Some common causes of genetic mutation are radiations, chemical agents called mutagens, etc.

2. Growth factors- these are the molecules that bind to receptor proteins to initiate a signaling pathway that can result in cell cycle.

3. Tumor suppressor genes- these are the genes responsible for stopping the cell to enter cell cycle. Inactivation of these genes can cause unregulated cell division.

4. Cell cycle checkpoints - during the cell cycle, a cell has to pass through certain checkpoints which make sure the continuity or stopping of the process. Problem in their regulation can cause uncontrolled cell division.

5. retroviruses- These are the viruses who have RNA as their genetic material instead of DNA. They replicate via DNA intermediate which when they insert inside a cell can start cell cycle.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer
