4. The CFTR gene is carried on human chromosome 7, an autosome. A recessive mutation in CFTR is the cause of cystic fibrosis disease. A female who doesn't have cystic fibrosis has a child with a man who also doesn't have the disease. Their first child has cystic fibrosis. What is the probability their second child will have the disease? A. 0 (definitely will not have it) B. 1/4 C. 1/2 D. 3/4 E. 1 (definitely will have it)

Review the Allelic Variants starting with .001, how does the information in brackets describe the mutation? Example: [CFTR, PHE508DEL] For each mutation (allelic variant) listed below, explain how the mutation would affect the production of: (20 pts total/4 pts each) the mRNA the protein encoded by the CFTR gene. Example: .0001 CYSTIC FIBROSIS [CFTR, PHE508DEL] The 508th triplet codon, which normally codes for phenylalanine, is deleted. Consequently, the CFTR mRNA is 3 nucleotides shorter than normal, and the CFTR protein...

Mutations in the CFTR gene result in
cystic fibrosis in humans, a condition in which abnormal secretions
are present in the lungs, pancreas, and sweat glands. In the effort
to positionally clone the CFTR gene, the gene was mapped to a
region of 500 kb on chromosome 7 containing three candidate genes.
Using your knowledge of the disease symptoms, how would you
distinguish between the candidate genes to decide which is most
likely to encode the CFTR gene?
How can you prove that your chosen candidate is the CFTR gene? Select the three correct...

(a) role of the CFTR receptor in the human body.
(b)
(c)
CFTR receptor in the human body, (B) the role of CTFR receptor and the cholera toxin in development of cholera (diarrhea and dehydration), and (C) the mutation responsible for the vast majority of cystic fibrosis as well as how this mutation results in cystic fibrosis.

Question 26 (4 points) Bonus question: The CFTR protein is found in the plasma membrane of individuals unaffected with cystic fibrosis. A common mutation in CFTR causes the protein to be trapped in the ER and eventually degraded. Why does this happen?
Cystic fibrosis is an autosomal recessive disease caused by a mutation in a single gene with...
Cystic fibrosis is an autosomal recessive disease caused by a mutation in a single gene with two alleles. Suppose the frequency of cystic fibrosis in a population is 3%. Assuming the gene is in HW equilibrium, calculate the allele and genotype frequencies. If the population consists of 100 individuals, how many are carriers (but unaffected) for the cystic fibrosis allele?
The CFTR gene is a eukaryotic gene, but how is the gene structured in terms of...
The CFTR gene is a eukaryotic gene, but how is the gene structured in terms of the numbers and lengths of exons and introns? "Sketch" a rough, but labelled diagram of the exon/intron structure of the CFTR gene and explain the significance of exons and introns and what such gene structures mean in terms of gene function. As part of the explanation, address the relationship between allelic variants and gene structure

The most common mutation occuring in people with cystic fibrosis is the loss of a single amino acid (phenylalanine) at position 508 of the protein. This mutation O a. is a point mutation b. is an single nucleotide polymorphism c. is a deletion of 3 nucleotides d. in an insertion of a single nucleotide e. is a chromosomal rearrangement → Moving to another question will save this response.
