A gerbil poplulation has one hundred light blue gerbiles, 250 dark blue gerbils, and 150 black gerbils. In one generation 10% of the home population is displaced by a gang of tough light blue gerbils. BB=light blue Bb= dark blue bb=black 1.) Use the data to calculate the allele proportions […]

1) Overexpression mutations can be oncogenic because the oncogene isa) translocated next to an active regulatory sequenceb) amplifiedc) altered in a regulatory sequenced) all of the abovee) none of the above 2) Translocation of a gene can produce a fusion product with uncontrolled protein kinase activity. An example of this […]

Q1. A rat tumour cell line proliferates rapidly in culture due to the fact that it expresses a high level of a constitutively activated Ras. You inject into these cells an antibody raised against guanine nucleotide exchange factor, SOS that blocks its binding to Drk. How will this influence the […]

Genetically modified organisms (GMOs) are created by inserting one or more genes into an organism’s genome. As you know, each gene codes for a polypeptide or protein, so by inserting a new gene we can get organisms to produce a new protein. A researcher would like to make a genetically […]
