The series of molecules that are activated form a signalling
pathway (Figure 3). Central to the signaling pathway are molecules
known as kinases and phosphatases. Protein kinases are molecules
that catalyze the addition of phosphate groups to proteins there by
activating them. Primarily they add phosphate to either tyrosine
residues or serine and threonine residues in proteins. Phosphates
are molecules that remove a phosphate group from a protein there by
de-activating the protein and resulting in shutting down of the...

Hagrid has purified a protein from unicom sweat and called UNI-1. He has then doned the Unit gone and inserted in rat zygotes (by microinjection) a recombinant construct containing the Uni-1 coding sequence its entire 5 UTR region, covering both the minimal promoter and a series of cutative regulatory als elements. The mutantrats develop glorious, luminous hair. Hagrid has also discovered that the UNI-1 protein binds very tightly to DNA and hypothesizes it is a transcription factor that regulates proliferation...

Question 10-12
10. During the mating process, yeast cells respond to pheromones secreted by other yeast cells. These pheromones bind GPCRs on the surface of the responding cell and lead to the activation of proteins inside the cell. When a wild-type yeast cell senses the pheromone, its physiology changes in preparation for mating: the cell stops growing until it finds a mating partner. If yeast cells do not undergo the appropriate response after sensing a pheromone, they are considered sterile....
