Explain what cell protein could be on or off too much to disrupt control of the...
Homework Answers
Cell cycle is highly regulated process whose regulation are done by several proteins including cyclin and cyclin depandant kinase(cdk).
These proteins are responsible to run the cell cycle in controlled way with coordination with mitogens. Once this proteins get disrupted or non-functional due to mutation in genes of cyclin and cdk then cell cycle start operating in uncontrolled way and leads to continous cell division mitosis process and that leads to cancer.
Hope it's clears.

A cancer cell undergoes cell division in an unregulated manner (for example, when no growth factors are present). Alterations of the following factors could cause cells to exhibit such ‘uncontrolled growth’ characteristics. Determine whether the gene encoding the specified factor behaves like an oncogene/proto-oncogene or a tumor suppressor gene. Briefly explain your reasoning. A kinase that functions in a growth factor signal transduction pathway. A CDK that functions in cell cycle regulation. A kinase that functions to turn off the CDK described in...

The picture below represents a cell during metaphase of mitosis. The chromosomes are represented in red and the mitotic spindle is represented in green. BO ! A. The cell is stuck in metaphase because a checkpoint has been activated. Why was the checkpoint triggered? B. What could have happened to this cell without this checkpoint? There are three main checkpoints during the cell cycle. One checkpoint occurs at the end of G1 phase and involves the protein p53. If p53...
