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.


Which type of genes if abnormally activated such that the protein is always present and active can result in cancer?

Abnormally activated proto-oncogenes can lead to cancer when they become oncogenes, resulting in the continuous production of proteins that promote cell growth and division. This overactivation can occur through mutations, gene amplifications, or chromosomal rearrangements. As a result, cells can proliferate uncontrollably, contributing to tumor formation. Examples of such oncogenes include RAS and MYC.


Viruses and chemical exposure can cause mutations in proto-oncogenes which can lead to?

onocogenes. Process: -PO (proto-oncogenes) are moved (closer to promoter/enhancer) -More PO is made -Proteins are made in excess (in more excess if it's been in excess from previous step) -Mutations at pts -At PO, causing increase expression -At coding gene, causing gene protein to resist degeneration


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.

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

oncogenes


What are proto-oncogenes and how do they differ from oncogenes?

Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.


Oncogenes are genes that A) fight cancer. B) suppress the normal activity of the immune system. C) can signal cells to reproduce uncontrollably. D) have mutated.?

Oncogenes are genes that C) can signal cells to reproduce uncontrollably. They typically arise from mutated proto-oncogenes, which normally regulate cell growth and division. When these genes become activated or overexpressed, they can lead to cancer development by promoting excessive cell proliferation.


When proto-oncogenes mutate they may become?

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.


Is it true or false that only individuals with cancer have proto-oncogenes?

False. Proto-oncogenes are genes that can potentially become oncogenes, which are associated with cancer development. They are present in all individuals, not just those with cancer.

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.
