During the embryogenesis, axial mesoderm cells are specialized to express different genes. We identified three group of cells present in close proximity. Among these groups one cell subtype (known as Sub1) have probability of 0.5 to express gene XRA. The other cell subtypes (known as Sub2 and Sub3) have a probability of 0.8 and 0.1 respectively.

Suppose that we isolated one of these cell subtypes at random and grow them in the lab to study gene expression patterns. We define two states for gene expression; as the state of success (S) if gene XRA is observed and failure (F) if not.

a) What is the probability (P(S)) of observing gene XRA expression?

b) Given that gene XRA will be expressed every hour. What is probability P(SFS) in the next three hours?

c) Assuming that we observed the sequence of SFF, what is the probability of that we isolated the subtype 2 cells during the embryogenesis?

Which of the following is a difficulty in getting prokaryotic cells to express eukaryotic genes? a. The signals that control gene expression are different for prokaryotes, thus requiring prokaryotic promoter regions to be added to the vector. b. The genetic code differs because prokaryotes substitute the base uracil for thymine. c. Prokaryotic cells do not recognize eukaryotic stop and start codons. d. The ribosomes of prokaryotes are not large enough to handle long eukaryotic genes.

Drosophila has three linked autosomal genes that determine different traits. These genes are black (b), vestigial (vg), and singed(sn). Each of the three genes has two alleles: a dominant wild type allele, indicated by a "+" (plus) and a recessive mutant allele indicated by a "-" (minus). (These mutant alleles cause dark black spots, short "vestigial" wings, and bent "singed" hairs, respectively, when homozygous). A testcross is conducted between females that all have the same genotype and are triple heterozygotes...

3) How is it that we all have the same genes, yet we can have different genotypes for a given gene that results in the expression of a different phenotype? This is not the same answer as the previous question. Again, I am looking for a description of what is happening on a molecular level to result in different phenotypes.
