Why would DNA polymerase be useful in a potential anti cancer drug?
DNA polymerase can fill the gaps in the DNA that are left by removal of damage bases. DNA polymerase can help cancer cells to tolerate DNA damage.
What is the difference between cancer cells and old cells?
Cancer cells are abnormal cells that divide uncontrollably and can invade nearby tissues, whereas old cells are normal cells that have reached the end of their lifespan and stop dividing. Cancer cells can cause tumors and metastasize, while old cells are usually cleared away by the immune system.
Why Cancer is a cell response to DNA damage that results in cell death?
Cancer is not a direct response to DNA damage leading to cell death; rather, it arises when cells accumulate genetic mutations that allow them to evade normal regulatory mechanisms. When DNA damage occurs, cells typically activate repair processes or undergo apoptosis (programmed cell death) if the damage is irreparable. However, cancer cells often develop mutations that enable them to resist apoptosis and continue dividing despite sustaining DNA damage. This unchecked proliferation leads to tumor formation and the progression of cancer.
What is meant by constitutional DNA and its role in cancer detection?
Constitutional DNA means the normal DNA of a patient with a cancer (from blood for example). It is possible to compare the constitutional DNA from healthy tissue to tumor DNA from the cancer to know the mutations that are important for tumor formation.
Why does UV light cause cancer?
UV light causes cancer by damaging the DNA in skin cells, leading to mutations that can result in uncontrolled cell growth and the development of cancer. Prolonged exposure to UV light, especially from the sun, increases the risk of skin cancer due to this DNA damage. UV light can also weaken the immune system's ability to repair damaged cells, further increasing the likelihood of cancer development.
Is cancer part of DNA?
Cancer is not part of DNA. Change in DNA. may cause cancer . Some people may be born with faulty DNA which might cause the cells that read the faulty section of DNA to reproduce uncontrollably, but on the other hand, exposure to radiation or carcinogens may cause the DNA in a few specific cells to mutate and thus not be controllable by the rest of the cells in your body.
What would happen if cells with mutated DNA replicated?
Cancer.
What is the relationship between DNA and cancer?
The relationship between Cancer and DNA cancer begins when mutations distrupt the normal cell cycle, causing cells to divide in an uncontrolled way.
Does radiation kill cancer cells?
Yes, radiation therapy works by damaging the DNA within cancer cells, which prevents them from dividing and growing. This ultimately leads to the death of the cancer cells.
Why would DNA polymerase be useful in a potential anti cancer drug?
DNA polymerase can fill the gaps in the DNA that are left by removal of damage bases. DNA polymerase can help cancer cells to tolerate DNA damage.
What characterises a cancer promoter?
A cancer promoter causes cells with DNA mutations to multiply and become tumors.
What happens in a cancer growth?
When the UV rays hit your skin it can cause damage to your DNA cells. this is called getting sunburned. when you get too much sun exposure and your DNA cells are damaged beyond repair then this might cause your DNA cells to break apart. this will cause more cells to form and when the cells reach the flesh it forms skin cancer.
Why does an atomic bomb give people cancer?
Radiation bombards your cells at a microscopic level destroying the DNA. When the DNA then replicates it has errors. The errors cause cancer, which is essentially when cells go wild and not in a fun way.
What is the difference between cancer cells and old cells?
Cancer cells are abnormal cells that divide uncontrollably and can invade nearby tissues, whereas old cells are normal cells that have reached the end of their lifespan and stop dividing. Cancer cells can cause tumors and metastasize, while old cells are usually cleared away by the immune system.
How is cancer classified?
Cancer is classified as an abnormal growth of cells. This may happen because of a mutation in the cells DNA. When the cells grow abnormal, it usually grows too fast.
Can a wasp sting on your breast give you breast cancer?
No. Breast cancer is in the cells and may also be DNA related.
What are the disadvantages of radio activity to humans'?
Radioactivity causes the destruction (mutation) of DNA in our cells, when these cells multiply they contain the mutated DNA which causes irregularities and cancer.
