Document Summary

Denaturaion-loss of protein structure and funcion; permanent or reversible; due to changes in ph, temperature, etc. Rna polymerase catalyzes transcripion process & adds nucleoides to 3" end mrna then goes through processing: 5" cap, poly-a tail, rna splicing. Iniiaion: elongaion, terminaion & disassembly trna (transfer rna) catalyzes translaion process: trna is charged by aminoacyl synthetase enzymes, aniicodon recognizes codon, ataches appropriate amino acid. Ribosomes bind with mrna, and it is on ribosomes that translaion takes place. Rna: mrna (info transcribed from dna), trna (recognizes codon and ataches appropriate amino acid), rrna (directs translaion of mrna into proteins) Cell communicaion: recepion, transducion, response, endocrine, paracrine, autocrine. Choice b: c: if you cannot match the item with either choice a or. Choice a: g protein coupled receptor choice b: receptor kinases. Involves receptor binding to a ligand to iniiate the signal c. 1: acivated receptor forms a pair or dimerizes. 3: opens up an ion channel as a response d.
