What do Proto-oncogenes regulate?
Proto-oncogenes stop cells dividing too often. When a mutation occurs to proto-oncogenes this is when cancer can occur, as there is then no hay-flick limit (normally cells have a limit to how many times then can divide) cells are able to replicate uncontrollably.
When proto-oncogenes mutate they may become?
They are called oncogenes.
How does small interfearing RNA kill cancer cells?
Small interfering RNA molecules can kill cancer cells by inhibiting the expression of oncogenes which give the cancer cells their cancerous properties.
Where can one learn more about oncogenes?
The best place that one can learn more about oncogenes is the American Cancer Society's official website. The site has a page dedicated to oncogenes and has a list of answers to common questions asked about the gene.
What do oncogenes normally encode for?
proteins that regulate cell growth

Regulatory genes in cells fail to function properly and allow cancer to develop what are they called?
oncogenes

They are called oncogenes.
What are the reason or factors due to which neuron do not divide?
To minimize cancerous growths. Division can get screwed up (oncogenes/proto-oncogenes) and you want to minimize the risk. This means that neurons do not cause cancer. Glial Cells (neuronal support cells) can cause cancer however because they retain the ability to divide.
How does small interfearing RNA kill cancer cells?
Small interfering RNA molecules can kill cancer cells by inhibiting the expression of oncogenes which give the cancer cells their cancerous properties.
How do DNA mutations affect cells?
Cells are dividing through the processes of Mitosis and Meiosis. DNA mutations directly affect cells by making them divide non-stop. This is known as Cancer. Proto-oncogenes, a gene involved in cell division mutates and becomes oncogenes that orders cell mechanism of division to go on continously even though the DNA found in a cell's nucleus is already damaged. this causes abnormal cell division.

Checkpoint genes that stimulate mitosis are called?
oncogenes
What has the author Manjusri Das written?
Manjusri Das has written: 'Selected abstracts on oncogenes and epidermal growth factor receptors' -- subject(s): Abstracts, Tumors, Oncogenes, Epidermis
How do eukaryotic cells make more cells?
Cell can make more cells via two processes. The first is called mitosis: a process which creates two identical cells. Both eukaryotic and prokaryotic cells can undergo mitosis. The second is meiosis: a process which produces reproductive cells in sexually reproducing eukaryotes. When a cell becomes cancerous, one or more mechanisms in the cell that control mitosis breaks down. This occurs due to a mutation in the cell's DNA. The genes in which a cancer-causing mutation can occur are either called proto-oncogenes or tumour suppressor genes. When such a mutation occurs in a proto-oncogene they become activated and become oncogenes. The product of oncogenes promote uncontrolled mitosis, hence the name onco(cancer)-gene. Again, as the name suggests, tumour suppressor genes have some role in suppressing cancer. Tumour suppressor genes are regulators of mitosis. When a cancer causing mutation occurs in a tumour suppressor gene, the product of the gene becomes disfunctional or are not produced altogether.
What do oncogenes normally encode for?
proteins that regulate cell growth
What is the cancer causing agents called?
A carcinogen.
