Document Summary

Understand, describe and demonstrate the steps involved in transcribing dna to mrna. Be familiar with the elements comprised in a transcripion iniiaion complex and its role. Compare and contrast transcripion in prokaryotes vs eukaryotes. Because it is not involved in the signal transducion cascade. Because it is a faty acid anchored protein. When it"s not the 3 subunits are bound together, when they reach the receptor and bind to it they need to be acivated and then separate. One part of the trimer (alpha subunit) goes on to solve the cascade. Ach can bind to 5 diferent types of cpcrs. Mediate responses to a diverse range of ligands (eg. neurotransmiters, hormones, odorants, tastants, and photons of light) Diversity of receptors for given ligand translates to muliple responses. These bind all sorts of ligands (from ach to adrenalin/light) all g-protein coupled receptors trigger 2 main pathways, camp and pip (ip3) camp pathway.
