Answer #1

Through the development, approximately one-fifth of the cells in each aggregate differentiated as prestalk cell while the remainder as prespore cells. prestock cell has two subclasses of prestock cell pst A cells and pst O cells. Dif-1 is produced by the prespore cells as part of the negative feedback loop that regulates the pst O to the prespore cell ratio. the ecm A-gene is directly induced by Dif-1 and in the dmtA- strain, mutant that defective in Dif-1 biosynthesis the pstA. specific marker is expressed but the pst-O specific marker is not. these facts suggest that Dif-1 is the physiological inducer of pst-O cell differentiation but not pst-A cell differentiation. by rt-PCR we can detect this expression level.

(5 pts) Genes D and E are located in the Drosophila genome. DE·DE females are crossed with de·de males to produce F1 flies that are heterozygous for both traits. What gametes do each of these parents make? F1 females were crossed with de·de males, and 2000 flies were examined. What gametes do each of these parents make?

8) You just isolated a new strain of mutant mice, and preliminary mating suggest that the new mutant phenotype is not inherited in an autosomal fashion. Circumstantial evidence seems to indicate that the mutant phenotype may be following either an X-linked dominant or a mitochondrial-type inheritance pattern. Assume the mice are true breeding. a) What informative crosses would you set up to distinguish between these two possibilities? b) How would you interpret your results? 9. You are crossing two individuals...

Retinitis pigmentosa is a genetic disease that causes the breakdown and loss of retinal cells. Retinitis pigmentosa often starts with decreased night vision and will progress to blindness as retinal cells die. Several genes have been linked to Retinitis pigmentosa, one of which is GADD. Mice lacking GADD (these mice were experimentally created so that the GADD region of the genome was deleted) have increased expression of non-retinal genes in retinal cells. In other words, in these mutant mice, genes...

1. Currently you are studying threonine synthesis in E. coli. To find genes whose protein products are important for threonine synthesis, you perform a mutagenesis to find mutants that require a source of threonine to grow. (a) Immediately after mutagenizing the bacteria, would you choose to grow the bacteria on rich media or on minimal media? Briefly explain your choice. Rich media. A mutant unable to make a particular amino acid will not be able to grown on media lacking...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
