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.

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...

I really need help with these questions!! 2. Bernard Davis tested the "cross-feeding" interpretation of some data that showed the phenotype of one microbe as capable of being changed by another microbe. His contribution can be summarized as: A) using one strain of microbes as food for another, and then evaluating the impact upon microbial phenotype. B) combining microbes with complementing auxotrophs in a single tube and then analyzing the cells of gene exchange. C) placing a barrier between bacterial...

Question 23 (1 point) The A and B alleles in ABO blood types can give rise to an individual that is blog type AB. This specific blood type is an example of: A) multiple alleles B) epistasis C) codominance D) partial dominance Imagine the gene encoding the lac repressor was mutated so that lactose (more technically allolactose) no longer bound to the repressor. However, the lac repressor was still capable of binding DNA at the operator sequence....
