The two types of cell cycle genes if mutated cause cancer cells to divide uncontrollably are called tumor suppressor genes and?
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
Why cancer is caused by multifactorial traits?
because it have two clases of genes involved: oncogenes and tumor suppressor genes
What are two types of genes that when disrupted can cause cancer?
The two genes considered responsible for the cause of cancer are the oncogene and the tumor suppressor gene.
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 is the function of a tumor suppressor gene in the human body?
Tumor suppressor genes help regulate cell growth and prevent the development of cancer by controlling cell division and repairing damaged DNA.
Where can one find information about Tumor Suppressor Genese?
You can find information about Tumor Suppressor Genes in Bio Portfolio, Chips Books, Cancer Res, Academic Research Microsoft, Nature,Freezing Blue, Cancer 2000.
What is the difference between DNA genes chromosomes?
Genes are basic units of Inheritance and are the templates for the creation of proteins, whereas Chromosomes are the molecular structures within the nucleus that contain genes.
Explain how mutations in tumor suppressor genes can contribute to cancer?
Well, tumor suppressor genes are basically proteins that regulate the eradication of cells that develop mutations in the G1 or G2 phase of the cell cycle. For example, lets say a 54 year old patient has the Trp53 tumor suppressor protein mutation. What this means is that this patient has less of an ability to sense cells with mutations in the pancreas because they are deficient or void of the tumor suppressor protein, Trp53. Thus, this patient has an increased risk of pancreatic Adenocarcinoma, the most common form of pancreatic cancer.
What are tumor suppressor and oncogenes genes?
Tumor suppressor genes are normal genes that carry out several functions: * slow down cell division * repair mistakes made when DNA is being replicated * tell cells when to die (a process known as apoptosis or programmed cell death) A mutation in a tumor suppressor gene allows cells to grow out of control, which can lead to cancer ie the growth of a tumor. About 30 tumor suppressor genes have been identified, including p53, BRCA1, BRCA2, APC, and RB1. A good analogy for tumor suppressor genes is the brake pedal on a car - it normally keeps the cell from dividing too quickly just as a brake keeps a car from going too fast. If the brakes on a car fail, the car goes out of control; similarly, when something goes wrong with the gene, such as a mutation, cell division can get out of control.

What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
What is an acoustic neuroma caused by?
caused by a change or absence of both of the NF2 tumor suppressor genes in a nerve cell. Every person possesses a pair of NF2 genes in every cell of their body including their nerve cells
What are three categories of genes that when mutated can lead to tumor formation?
· 1) Genes involved in cell division · 2) Oncogenes o Dominant-acting stimulatory genes o Normally low levels or expression is turned off o Mutation causes increased/hyper expression · 3) Tumour suppressor genes o Recessive-acting genes o Normally expressed to inhibit cell division o Mutation causes defects in product or no expression
