Suppose that you compare the levels of nonsynonymous and synonymous substitutions (i.e. you perform the kA/kS test) on a particular coding region of a gene. You find that kA/kS = 0.3.

(a) What type of selection, if any, would this result support?

(b) You also examine levels of polymorphism around this particular gene in a sample of 20 individuals from the population of interest. You find that Tajimaâs D is -2.8. What type of selection, if any, would this result support?

The ABO gene non chromosome 9 exists as one of the three possible alleles . Each allele has a different genetic sequence, determining the protein produced via transcription and translation of the gene. Perform a literature search and come to your conclusion about which allele (i.e blood type) is probably the original human blood type. Briefly state your evidence, as you see it for your conclusion

1) Why are genes whose products are required for normal growth not carried on plasmids? List some genes that you would not expect to find on a plasmid and some genes you might expect to find on a plasmid.

2) The ampicillin resistance gene of plasmid RK2 is unregulated. The more copies of the gene a bacterium has, the more gene products are made. In this case, the resistance of the cell to ampicillin is higher the more of these genes it has. Using this fact to devise a method to isolate mutants of RK2 that have a higher than normal copy number (copy up mutations). Determine whether your mutations have mutations in the Rep-encoding gene.
