Why are tumor-suppressor mutations associated with cancer typically lof mutations?
Homework Answers
Tumor suppressor genes are normal genes that slow down cell division, repair DNA mistakes, or tell cells when to die (a process known as apoptosis or programmed cell death). When mutation occurs in the gene, loss of function mutation,then cell division gets out of control and results in cancer.

BRCA1 and BRCA2 are tumor suppressor genes that have been associated with breast cancer development due to mutations of these genes being linked to a subset of breast cancers. If an individual carries one nonfunctional copy of the BRCA gene, will all of their cells be affected? Explain.

Given that TP53 is a recessive gene and is not located on the X chromosome, why would people who inherit just one mutant copy of a recessive tumor-suppressor gene be at higher risk of developing cancer than those without the recessive gene?

TS =Tumor Suppressor genes
O = Oncogenes
5A. (12pts) Cancer is a genetic disease. Some of the causative mutations are Tumor Suppressor genes, and others convert proto-oncogenes into Oncogenes. In the list of properties below, mark an X in the column for TS, O, or both. TS O both Causes of inherited elevated cancer risk. Leads to uncontrolled cell growth. Typically, spontaneous, gain-of-function mutations. Can cause increased DNA damage. Dominant in...

1. Inflammation can play a role in cancer (development and/or progression) in which of the following ways? Select all that apply. Question options: A) TILs can secrete pro-inflammatory cytokines that promote cancer. B) TAMs can attack cancer cells and destroy them. C) Ulcerative colitis can progress to colon cancer. D) Immune cells associated with a cancer can secrete angiogenic and growth factors. E) Hepatitis C infection can lead to liver cancer. F) Hypercholesterolemia can develop into leukemia. 2. Tumor suppressor...

Which of the following is a false statements about tumor suppressor genes? Gene amplification (duplication) of a tumor suppressor gene is less likely to result in cancer than gene amplification of a proto-onocogene. Individuals with a single normal copy of a tumor suppressor gene are more prone to cancer than those with two normal copies. Inactivation of tumor suppressor genes can lead to enhanced cell survival and cell proliferation. Epigenetic changes that silence tumor suppressor genes would not lead to...
