An individual's risk of developing cancer is influenced by genetic as well as environmental and lifestyle factors is true with respect to the genetic risk of cancer. Option (1)

Cancer cannot be inherited by a kid from a parent. Moreover, tumor cell genetic alterations are not transmissible. Yet, if a genetic alteration that raises the risk of cancer is found in a parent's sperm or egg cells, it can be passed down (inherited).

What exactly is a cancer risk gene?

The p53 or TP53 gene is the one that is most frequently altered in cancer patients. Almost 50% of tumors have a defective or absent p53 gene. Most mutations in the p53 gene are acquired. Although germline p53 mutations are uncommon, those who have them have an increased chance of developing a wide range of cancers.

C. The amounts of A,T,G and C in DNA is constant across  species. Any species' or organism's DNA should have an equal amount of guanine and cytosine.

As well as adenine and thymine, according to Chargaff's standards. It is expected that the purine and pyrimidine bases have a 1:1 stoichiometric ratio, or A+G=T+C.

Erwin Chargaff made some crucial findings about the nitrogenous bases in DNA. He determined the relative amounts of the bases A, T, G, and C in DNA of various organisms.
