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.
Homework Answers
Breast cancer is associated with abnormal genes. BRCA1 and BRCA2 are the inherited genes that produce tumor on the breast. This can be inherited from mother or father. If the individual carries one nonfunctional copy of gene mutation, then there is a 50% chance of risk of developing breast cancer. That means one copy of an altered gene of BRCA is enough to develop breast cancer. The studies also show that 72% of women with BRCA1 inherited gene mutation and 69% of women with BRCA2 gene mutation develops breast cancer by the age of 80.

Consider a spontaneous mutation in the gene HER2, a tumor suppressor involved in cell cycle control Mutations happen at a rate of about 1 error per 109 bases per generation. A spontaneous deleterious mutation must occur in HER2 specifically, and not in another gene. The likelihood that a spontaneous mutation is deleterious and could lead to cancer depends on the number of mutable bases in HER2, the fraction of bases that will affect the function of HER2, and that both...

please answer all the question to get a like. Part III Dr. Hernandez sits down with Ann and her partner. The doctor is sorry to report that Ann has breast cancer; however, because it was caught early and responds to estrogen and progesterone, the prognosis is good. At this point it looks like the cancer is stage 1. However, as Ann is young, the doctor wants to perform a couple of tests. The first test is a genetic sequencing test...

The Case Study in Cancer Part I Ann is a 27-year-old nurse working at the local hospital in surgery. She had worked hard to move into the specialty, and she was enjoying her career, friends, and family. She and her partner had been living together for about a year, and she was content. As a nurse, Ann knew the importance of doing breast self-exams, and did them regularly. In the shower one morning, she felt a lump she wasn’t familiar...
