Question no:1
Correct answer: 50%
Male (son) has one X chromosome and one Y chromosome. So probability of their son having mutated allele is 50% i.e., X chromosome can come from mother or can't not come from mother. So this are the only two possible condition. So 1/2 is 50%.
Question no 2.
correct answer:
'Is a small circular piece of DNA independent of chromosome'
and ' May be used as a vector to introduce gene into cell'
A plasmid is small circular, self replicating piece of Extra chromosomal DNA . It is used as vector to transfer desire gene in the field of Recombinant DNA technology.

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?

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.

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...

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...

The BRCA1 protein is coded for at position 5677 on chromosome 17. Mutations in the BRCA1 gene are associated with elevated risk of breast cancer. BCPR is another gene on chromosome 17. BCPR codes for tp53, a tumor-suppressor protein. When functioning properly, tp53 reduces the chances of tumor growth for multiple cancers, including breast cancer. For simplicity, we will call healthy BRCA1 alleles 1+ and malfunctioning BRCA1 alleles 1-. We will call healthy BCPR alleles 2+ and malfunctioning BCPR alleles...

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...

1-1. You wish to insert a gene involved in the degradation of a toxic compound into a plasmid, and then use the plasmid as a vector to transform a species of bacteria so that it can be used in a bioremediation effort to clean up hazardous waste. In order to accomplish this, you will need to ______. SELECT ALL THAT APPLY. -digest both the gene and plasmid with the same restriction enzymes in order to yield appropriate "sticky ends" that...

Elizabeth, age 27, had heard about the discovery of the gene and
about the mutation linked to Jewish women. Her paternal grandmother
had been diagnosed with breast cancer at age 51 and died two years
later, and Elizabeth worried that she may have inherited a variant
that would put her at increased risk.
She also worried about her mother, age 52 and apparently
cancer-free so far, and her 7- year old daughter.
Her daughter is not allowed to participate in...
