How do tumor suppressor genes work to prevent the development of cancer?
Tumor suppressor genes help prevent cancer by regulating cell growth and division. They can repair damaged DNA, trigger cell death, or stop cells from dividing uncontrollably. When these genes are mutated or inactive, cells can grow out of control, leading to the development of cancer.
What would happen if cells with mutated DNA replicated uncontrollably?
If cells with mutated DNA replicated uncontrollably, it could lead to the development of cancer. This is because the mutations can cause the cells to grow and divide rapidly, forming tumors that can invade nearby tissues and spread to other parts of the body.
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.
What is a malignant gene?
A malignant gene is a gene that has mutated and is involved in promoting cancer growth and progression. These genes can be oncogenes, which promote cell proliferation, or tumor suppressor genes, which normally inhibit cell growth but are inactivated in cancer.
What are the most commonly mutated genes in cancer and how do they contribute to the development and progression of the disease?
The most commonly mutated genes in cancer are TP53, KRAS, and PIK3CA. These mutations can lead to uncontrolled cell growth, resistance to cell death, and increased ability to spread to other parts of the body. This contributes to the development and progression of cancer by allowing the cancer cells to grow and divide uncontrollably, evade the immune system, and invade surrounding tissues.
What is the difference between a tumor suppressor gene and an oncogene?
Oncogenes regulate cell division, so if it is placed near an overly active gene, it may itself become overly active, thus causing cancer. Tumor suppressors suppress tumors and will only cause cancer if it stops its activity, contrary to oncogenes.
What does 'genetically predisposed to cancer' mean?
it means that because some close member of your family has cancer you have a high probability of developing cancer. To be a little more in depth, you inherit genes from both parents, like the genes that give you your skin tone, hair color, eye color, etc. You also inherit two genes called cell cycle genes, or better known as Tumor Suppressor Genes. Being 'predisposed' means you've inherited one good tumor suppressor gene and one mutated copy (gene). One good copy is enough to prevent your cells from dividing abnormally. So you can be born with one mutated copy, but not actually get cancer unless the other copy accidentally gets mutated at some point in your life. For example, mutations from the second copy could be the result of UV light from the sun, like in the case of melanoma. Since you have been born with one mutated copy already, you are predisposed to getting cancer.
What is the disorder in which some of the bodys cells grow uncontrollably?
Cancer is the disorder in which some of the body's cells grow uncontrollably. This abnormal growth can result in the formation of tumors and can interfere with normal body functions.
What Mutated genes that cause cancer are?
colonoscopy
What is the disease where the body's own cells lose the ability to control growth called?
The disease is called cancer. It occurs when normal cells undergo genetic mutations that cause them to divide uncontrollably and form tumors.
What does bladder cancer do to the normal cells?
Bladder cancer will force normal cells to divide uncontrollably.
How does the pathogen of lung cancer attacks and spread from one person to another?
Cancer is not caused by a pathogen, it is caused by a mutated cell which multiplies to create more mutated cells and so on.
