Chapter 18, Problem 6P
a. Explain how you could use worms transformed with myo-2::GFP to find mutations that disrupt the structure of the pharynx. How would the presence of the transgene facilitate the mutant screen?
b. Nematodes homozygous for loss-of-function mutations in a gene called pha-4 have no detectable pharyngeal structures. How could you use myo-2::GFP to determine if pha-4 is a master regulatory gene that directs development of the pharynx in a manner similar to the way Pax-6/eyeless controls eye development? (Hint: Review Solved Problem I.)

Using Figure 20-17, explain how the mutation in theGATA sequence of the Duffy gene imparts resistance toP. vivax infection.
The exchange of materials between RPE cells and the rods and cone cells is very important. Suggest by which membrane transport methods ions, proteins and damaged fragments of rod cells would be taken into the RPE cells. Outline the properties of stem cells which will help to repair the RPE layer of a patients retina after implantation of the thin sheet of cells. Outline how the presence of a base substitution mutation in the ABCA4 gene would result in the synthesis of a protein which cannot carry out its normal function. Need short answer in text solution and ASAP .
(1) Why the ratio of PE/GFP fluorescence is measured in the FACS experiment, instead of measuring only total PE fluorescence? (2) Explain the effect that each mutation causes in the function of MC4R, and how they can be linked to disease.
