Answer #1

Answer: (A) Proto-oncogenes are commonly activated in transformed cells by point mutations or gene amplification.

Explanation: A proto-oncogene is a gene with normal function, that can convert into a cancer-causing oncogene through mutations or amplified expressions.

Other options are incorrect because:

(B) Tumour suppressor genes normally keep a check on rampant proliferation of cells, thereby preventing cancer

(C) In cancerous cells, the tumour suppressor genes get inactivated and hence cancer is caused

(D) Oncogenes are ought to remain unexpressed since they code for certain proteins that can transform a healthy cell into a cancerous cell

(E) Tumour suppressor genes are completely different set of genes and are not genomically related to proto-oncogenes.

Oncogenes, Tumor-suppressor genes, and tumors For each of the following situations, provide a plausible explanation for how it could lead to unrestricted cell division. Colon cancer cells often contain mutations in the gene encoding the prostaglandin E2 (PGE2) receptor. PGE2 is a growth factor required for the division of cells in the gastrointestinal tract. Adenovirus, a tumor virus carries a gene for the protein E1A, which binds to the retinoblastoma protein (Rb).

Cells can become transformed (i.e., become capable of growing and dividing inappropriately, or become tumor cells) because of mutations in genes such as proto-oncogenes and tumor suppressor genes. Protein P, normally stimulates apoptosis or cell death when activated. Consider a cell with a mutation in one allele such that protein P is always expressed and active, while the other allele of gene P is deleted. Which of the following is true for this cell? options Gene P is a proto-oncogene,...

Cancer can be defined as an abnormal proliferation of cells that defy the normal regulatory controls observed by normal cells. Recently, histone deacetylation therapies have been attempted in the treatment of certain cancers [reviewed by Delcuve et al. (2009)]. Specifically, the FDA has approved histone deacetylation (HDAC) inhibitors for the treatment of cutaneous T-cell lymphoma. Why does histone acetylation might be associated with cancer? Low acetylation rates often lead to increased cell proliferation, the major cause of tumor. Normally, acetylation...
