A defective P53 gene is likely to cause poor regulation of cell cycles. P53 is a protein that suppresses tumor production and is implicated as a factor in cancer development. It prevents genome mutation and damage. 50% of human tumors have mutated or deleted P53 genes.

What cancers does the p53 cancer gene cause?
P53 it is an anzyme that monitorize the DNA and protect them from demagis.It is founded that its defective in 60% of cancer cells
Which defective protein is associated with the cells of half of all human cancers?
The defective protein associated with half of all human cancers is p53, also known as the "guardian of the genome." It plays a critical role in regulating cell division and can promote cell death in damaged cells. Mutations in the p53 gene can lead to uncontrolled cell growth and contribute to tumorigenesis.
What role does p53 have in controlling cell division?
Cell division is regulated by the p53 gene and relates to cancer because Cancer is caused by uncontrolled cell divison
What is the P53 gene function?
The p53 gene is a tumor suppressor gene that helps regulate cell growth and prevent mutations that can lead to cancer. It plays a crucial role in detecting damaged DNA and either initiating DNA repair processes or promoting the destruction of cells with irreparable DNA damage.
What is the role of P53 in Cell Cycle Check Point?
The p53 Tumour suppressor gene is located on chromosome 17. As its name suggests, it has an anti-tumour activity. That involves the overseeing of the cell cycle. If either the cell or the DNA is impaired, p53 activates the production of specific chemicals (like p21 protein), which interferes with the cell cycle. Depending on the nature/extent of the damage, its either repaired, thus cell cycle is allowed to continue, or p53 initiate apoptosis (cell death). This mechanism would effectively stop the proliferation of infected (malignant) cells, however, p53 itself (or any of genes/chemicals p53 regulates) could be damaged/mutated. In the inherited condition, Li-Fraumeni syndrome, for example, only one functional copy of p53 gene is inherited (instead of two), which interferes with its normal function.
What type of gene is the p53 gene?
The p53 gene is a tumor suppressor gene. It plays a crucial role in preventing the formation of cancer by regulating cell division and DNA repair processes. Mutations in the p53 gene can lead to uncontrolled cell growth and contribute to the development of cancer.
What is p53 called?
"The Guardian Angel Gene"
What would you expect cells to be like if they did not have properly functioning p53?
Cells without properly functioning p53 would likely have impaired ability to control cell growth and repair damaged DNA, leading to uncontrolled cell division and potentially increased risk of developing cancer. p53 is an important tumor suppressor gene that helps regulate these processes and maintain genomic stability.
Who identified the p53 gene?
The p53 gene was identified by a team of researchers led by Dr. David Lane and Dr. Arnold Levine in 1979. The protein encoded by the p53 gene plays a critical role in suppressing tumor formation and is often referred to as the "guardian of the genome."
What is p53 and how does it work?
p53 is a tumor suppressor gene that helps to control cell growth and prevent cancer development. It plays a critical role in protecting cells from DNA damage by either repairing the damage or inducing cell death if the damage is severe. When activated, p53 can signal for cell cycle arrest, DNA repair, or apoptosis (programmed cell death) to eliminate cells with irreparable damage.
What is p53 marker?
p53 is a protein that acts as a tumor suppressor, helping to prevent the formation of cancerous tumors. It is often used as a marker for cancer because mutations in the p53 gene are commonly found in various types of cancer cells. Detection of p53 abnormalities can help with cancer diagnosis and prognosis.
Does The p53 gene codes for a protein that triggers uncontrolled cell division?
No, when it detects a mutation or damage to the DNA of a cell it codes for a protein that causes apoptosis to occur which is the controlled death of a cell. so it prevents uncontrolled cell division.
