A mutation results in an enzyme that is partially active compared to the wild -type allele. This type of "leaky" mutation is classified as ________. A) null/ amorphic B)hypomorphic C) hypermorphic D) neomorphic E) dominant negative

a)  5 nuclear RNA polymerases   b)  3 nuclear RNA polymerases . c)  6 nuclear RNA polymerases   d)  none of these is true Eukaryotic cells contain ___________________ that transcribe distinct classes of genes.

Many oncogenes result from mutations that cause excessive expression of a protein in cells where it is normally not expressed or is expressed at inappropriate times during development. This type of mutation can be described as ________. A) amorphic B) hypomorphic C)hypermorphic D) neomorphic E) dominant negative

a) Sam wants to alter his interrupted mating experiment by placing a filter in between the donor and the recipient cells in order to separate the two. Is Sam’s suggestion for this modification to the procedure utilized in interrupted mating experiments valid? Explain.   b) Much to the dismay of the researcher with whom Sam is working, Sam is not only forgetful, but he is also lazy! Rather than devoting the necessary hours to conducting his assigned interrupted mating experiments, Sam has decided that his time would be better spent modifying the F plasmid so that the experiments wouldn’t require quite so much time. The diagram below shows a map of the E. coli F plasmid, similar to that shown in lecture. Sam is determined to “get rid of some of the excess DNA” present in the plasmid. Please keep in mind that the PI in the lab in which Sam works utilizes these F plasmids for interrupted mating experiments between Hfr and F- cells as well as for interrupted mating experiments involving F+…
