Chapter 24, Problem 1S
The FOX2 gene is associated with speech in human. It is also found in chimpanzees, gorillas, orangutans, rhesus macaques, and even the mouse, yet none of these mammals speak. Develop a hypothesis that explains whyFOXP2 supports speech in humans but not other mammals.

Based on the NCBI Blastp and reciprocal analysis, are there any mutations to suggest that mus musculus is a good model to test the human FGFR3 gene. This is the only model we have to go off of to predict whether a mouse is suitable. I can’t seem to grasp what exactly I’m suppose to look for in these two photos.
Pax6 is a gene that is involved in mammalian eye development. Mutations in this gene result in a lack of iris in humans, and mice that are homozygous for the mutation lack eyes completely. Mutations in the eyeless gene in the fruitfly Drosophila result in reduced eyes. Expressing Pax6 from mammals in other tissues of Drosophila during its embryonic development can result in an ectopic eye (e.g. an eye expressed in a different tissue type). An example of an ectopic eye on the antenna of Drosophila is shown below.
Part A:
The eye of humans, mouse, and fly are an example of the following (check all that apply)
A. Structural analog
B. Structural homolog
C. Developmental homolog
D. Genetic homolog
Part B:
Darwin's hypothesis of natural selection has two components:
Species are not static but change through time
Species are related, and not independent.
In what ways does the human, mouse, and fly eye support or contradict one or both of the two components of…
The phenotype of a heterozygous mouse (Aa) is agouti. The agouti banding pattern is due to altered expression of the agouti gene. Which of the following statement is false?
a) Expression of the agouti gene inhibits the production of eumelanin.
b) Evidence suggests that the agouti gene is only expressed in tissues associated with fur production.
c) Epigenetic markers silence the agouti gene resulting in dark pigmentation at the tip and root of the hair.
d) All of the above

This Notch/Delta-regulated system results in clusters of cells where the central one differentiates into a specialized hair cell. To better understand this system you have tagged the C-terminal cytoplasmic domain of Notch with GFP. You have done a forward genetic screen to look for mutants that have unusual phenotypes in this Notch system. The first one is a mutation in Notch itself. This mutant is in the ADAM10 cleavage site and blocks proteolysis. Draw the expected outcome for such a mutant: GFP localization and developmental outcome 24hr after differentiation.

- Termicin is a small antifungal protein in termites that is produced by cells and secreted into termite saliva in response to a pathogen. In vitro translation of the termicin-encoding gene is performed, and the effects of that product are compared to those of termicin extracted from a termite. You see that extracted termicin exhibits more antifungal behavior than in vitro translated termicin. After further analysis, you see that extracted termicin contains 3 disulfide bonds, while in vitro translated termicin contains zero. The addition of microsomes to the in vitro translation reaction results in termicin with all 3 disulfide bonds. What experimental condition is most likely responsible for this difference? A. in vitro translation was not performed at the correct temperature affecting protein folding B. a mutation occurred during in vitro translation, leading to differences in disulfide bond formation O C. the UPR can not be activated in vitro, therefore, this protein can only be…arrow_forwardDiscuss the similarities and differences between the bithorax and Antennapedia complexes in Drosophila and the Hox gene complexes in mice.arrow_forwardThe FOXP2 gene is sometimes called the “language gene.” Why is this name inaccurate?arrow_forward
