Textbook Question
Chapter 22, Problem 27P
Through GWAS explorations, scientists have identified several SNPs linked to obesity in people who live in the United States. One of these SNPs was within a gene called FTO. Interestingly, a common FTO variant is associated with obesity, but only in people born after 1945. Moreover, the later the birth year, the higher the risk for obesity associated with this variant of FTO. Why would a genetic risk factor for obesity vary by birth year?

Why the process of DNA is transcribed into mRNA and then translated into protein is referred to as the “central dogma” of biology?
Give one scenario that would explain how a mutation in the DNA of the Piedmontese bull could lead to muscle hypertrophy.
If more cows had the same musculature as the Piedmontese bull, how would that affect meat production in countries that use cows as a primary meat source?
Comparisons between human and chimpanzee genomes indicate that a gene that may function as a wild-type or normal gene in one primate may function as a disease-causing gene in another [The Chimpanzee Sequencing and Analysis Consortium (2005). Nature 437:69–87]. For instance, the PPARG locus (regulator of adipocyte differentiation) is a wild-type allele in chimps but is clearly associated with Type 2 diabetes in humans. What factors might cause this apparent contradiction? Would you consider such apparent contradictions to be rare or common? What impact might such findings have on the use of comparative genomics to identify and design therapies for disease-causing genes in humans?
An SNP is found associated with individuals who have diabetes. Which statement is true?
A. All individuals with the SNP will have diabetes.
B. The SNP codes for a faulty protein that causes the individual to have diabetes.
C. To identify the SNP in more individuals, they will need to have their genome sequenced.
D. The SNP may be linked to a gene that contributes to diabetes.

- One unexpected result of the sequencing of the human genome was the finding that mutations in a single gene can be responsible for multiple distinct disorders. For example, mutations in the RET gene can cause two different types of multiple endocrine neoplasias, familial medullary thyroid carcinoma, and Hirschsprung disease. How do you think mutations in a single gene can have such diverse effects?arrow_forwardEpigenetics may be partially responsible for the childhood epidemic of obesity.

How many new mutations would you expect each person to carry, on average, based on this mutation rate? Other studies have estimated that each person carries about 100 new loss-of-function mutations. How does this number compare with your estimate of the number of mutations based on the mutation rate? What might account for any differences?arrow_forward

Based on what you have learned in this unit about gene expression, what must the scientists do to the DNA sequence of the human insulin gene BEFORE inserting it into the bacteria, in order to have them produce the same insulin sequence that humans would produce?

- Huntington disease (HD) is an inherited neurodegenerative disorder characterized by gradual, irreversible impairment of psychological, motor, and cognitive functions. Symptoms typically appear in middle age, but onset can occur at almost any age, and the course of the disease can range from 15 to 20 years. The molecular basis of HD is becoming better understood, and the genetic mutation has been traced to a gene that encodes a large protein of unknown function. In individuals who will not develop HD, a region of the gene that encodes the N-terminus of this protein has a sequence of CAG codons (for glutamine) repeated 6 to 39 times in succession. In individuals with adult-onset HD, this codon (3 nucleotides) is typically repeated 40 to 55 times In those with childhood-onset HD, it is repeated more than 70 times. *codon: refers to the 3 nucleotides that code for amino acid. A small portion of the coding sequence of the HD gene is given below. The nucleotide sequence of the DNA is…arrow_forwardpeople with osteogenesis imperfecta have a dominant mutation in one of the two genes that produce type 1 collagen. people with OI have weak bones, bkuish color in teh whites of eyes, and a variety of afflictions that cause weakness in their joint and teeth.
