Researchers can manipulate the
genes of a mouse so that a single gene in a single tissue either
produces an inactive protein (a knockout mouse) or produces a
protein that is always (constitutively) active. What effects on
metabolism would you predict for mice with the following genetic
changes?

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

Background: Several genetic regions are needed for lactose
metabolism: P(promoter), O(operator), lacZ(b-galactosidase gene),
lacY(permease gene), lacA(transacetylase gene) and lacI(repressor
gene). Strains can be defined as having + - c or s copies: + refers
to the functional version, - refers to a defect version, c refers
to a constitutively active version and s refers to a superrepressor
version. Each strain may or may not have an extra-chromosomal
plasmid containing the genes indicated. TA=transacetylase

The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
