Document Summary
Levels of regulation: chromatin structure, remodeling, open, close, histones, acetylation, de-acetylation, activators, repressors, transcription, activators, repressors c, dimerization, affinity to dna (ligand dependent/ phosphorylation dependent) Location: repressor, activator, rna processing (changing the levels of rna and proteins, splicing (alternitive splicing, poly a tail c. Sensitivity to endo (inside) and exonucleases (outside: rna degradation, translation, protein modification, protein degradation, ubiquitin ligase. Transcription (activators and repressors, that work to regulate or modify the level of transcription) Chromatin remodeling complex (responsible for opening up certain parts of genome in response to changes in histone. Methylation of histones to close up dna. General transcription factors (attract rna polymerase, don"t provide specificity) Specific transcription factors, helicase, and chromatin remodeling process, Exonuclease that chews back on poly a tail (non-specific) Endonuclease has sequence specificity that cuts mrna in a specific spot. Ribosomes (50 proteins, 2 parts; top and bottom part and. Rna"s in there to give specificity and give shape)
