An oncogene is?
An oncogene is a gene that has the potential to cause cancer. They can promote cell growth or prevent normal cell death, leading to uncontrolled cell division and tumor formation. Mutations in oncogenes can contribute to the development of cancer.
How does a proto-oncogene differ from an oncogene?
A proto-oncogene is a normal gene that helps regulate cell growth and division, while an oncogene is a mutated form of a proto-oncogene that promotes uncontrolled cell growth, leading to cancer. Proto-oncogenes can become oncogenes through mutations that cause them to be constantly activated or overexpressed.
Is radiation more harmful to normal cells than to cancerous cells?
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
What is a mutation that forms an oncogene that changes normal cells into cancerous cells?
to a gene
An oncogene is?
An oncogene is a gene that has the potential to cause cancer. They can promote cell growth or prevent normal cell death, leading to uncontrolled cell division and tumor formation. Mutations in oncogenes can contribute to the development of cancer.
What is pro- oncogene?
An oncogene is a gene, when mutated or expressed at high levels it helps turn a normal cell into a tumor cell.
How does a proto-oncogene differ from an oncogene?
A proto-oncogene is a normal gene that helps regulate cell growth and division, while an oncogene is a mutated form of a proto-oncogene that promotes uncontrolled cell growth, leading to cancer. Proto-oncogenes can become oncogenes through mutations that cause them to be constantly activated or overexpressed.
Will normal or cancerous cells have a higher growth rate?
the cancerous cells
What are the key differences between normal tissue and cancerous tissue?
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
What is proto-oncogen?
A proto-oncogene is a gene that plays a role in normal cell growth and division. When mutated or activated, it can become an oncogene, promoting uncontrolled cell growth and potentially leading to cancer. Examples include growth factor receptors and signaling molecules.
The process in which a normal cell become a cancerous cell is called what?
Dysplasia
What is it called when normal body cells turn cancerous?
Carcino-Genesis.
Why do oncogene acts as though it is stuck in the on position?
Oncogenes are mutated versions of normal genes (proto-oncogenes) that can promote uncontrolled cell growth and division. These mutations can cause the oncogene to be stuck in the "on" position, leading to continuous activation of cell proliferation pathways and contributing to the development of cancer.
Is radiation more harmful to normal cells than to cancerous cells?
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
What goes wrong with a normal cell when it becomes cancerous?
A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.
