Textbook Question
Chapter 45.3, Problem 3EQ
CoreSKILL » Assume that the mean weight of both groups of mice—wild-type and transgenic—prior to being switched to the high-fat diet was 24 g. Calculate the approximate mean weights of the two groups at the conclusion of the study. How does a diet containing 35% of its calories from fat compare to a typical human diet?

1a) In a very large population, if the forward and reverse mutation rates are exactly the same, how would you expect the frequency of an original, non-mutated allele to change in the population over time? Will the population eventually achieve an equilibrium value of the frequency of the non-mutated allele?
b) What if the forward mutation rate is one order of magnitude larger (e. 10X) than the reverse mutation rate? Do you expect the frequency of the original, non-mutated allele to increase, decrease, or stay the same over time?
c) If the population size is considerably smaller, does this change your expectations for changes in the frequency of the original, non-mutated allele over several generations?

Q.1 These Graph Shows?
Part 1: Describe the differences in SNP diversity and LD structure observed between African and non-african populations. Part 2: Explain why these differences are expected from the evolutionary history of modern humans. Part 3: How do these differences impact association studies in terms of SNP array design and identifying causal variants at significant loci?

- WHAT IF? Since the results support a role for mouse FOXP2 invocalization, you might wonder whether the human FOXP2 protein is akey regulator of speech.

- INTERPRET DATA Compare the two graphs in Figure 1-17. What information does the second graph illustrate? What possible explanation can you give for the differences shown in the two graphs? (a) Number of chimpanzees who successfully employed specific method of tool use. (b) Number of chimpanzees who successfully employed learned method of tool use two months later.

Noonan et al. 2005. Science 309:597–599) set out to study the genome sequence of an extinct species of cave bear. They extracted DNA from 40,000-year-old bones from a cave bear and used a metagenomic approach to isolate, identify, and sequence the cave-bear DNA. Why did they use a metagenomic approach when their objective was to sequence the genome of one species (the cave bear)?arrow_forwardQ5. In lab 6, you will set up a PCR reaction to yield amplified DNA products of the rpo B(RNA polymerase B) and 16s rRNA genes. In lab 7, you will set up a sequencing reaction using about 40 ng of these PCR products that you will then add a sequencing primer to the sequencing reaction. If a sequencing reaction is set up with a 100-fold excess of primer to the PCR-amplified DNA product you want to sequence, calculate the number of sequencing primers you will need to add to this sequencing reaction. To perform this calculation, assume your 40 ng sample of double stranded DNA is 4,000 base-pairs (bp) long. Using these two variables of your PCR product [length (in bp) and amount (in g, grams)], you can calculate the number of DNA molecules being sequenced with two conversion factors using the formula below: The average weight of 1 bp is approximately ~650 (g/mole)/bp Avogadro’s number which is 6.02 X 1023 molecules/mole The easiest way to solve this problem is to figure out how much one…arrow_forward

Human mitochondrial genomes code for 37 genes but mitochondria produce only 13 proteins. What would most likely account for mitochondrial genomes having more genes than needed to code for the proteins produced? A. Several genes code for products that are not translated. B. Several genes have been inactivated over evolutionary time and no longer code for proteins. C. Several genes, and the proteins they code for, are of viral origin. They are not human mitochondrial genes. D. Several genes are coded on both the top and bottom strands of DNA. Therefore, they code for the same proteins.arrow_forward
