RNA polymerase transcribes genes How is this process regulated? How is specificity achieved? Key players transcriptional activator proteins -bind to specific sites on DNA and turn on the expression of nearby genes. Two adhesive surfaces one binds DNA, the other interacts with, and recruits RNA polymerase
Eukaryotic Chromosomes are composed of DNA, Histone and Nonhistone Proteins Histones: H1 H2A. H2 B, H3, H4. The later 4 form nucleosomes(100 A)and thus called core histones. H1 plays a role in forming 300 A superhelix Histones are rich in basic amino acids Nonhistone proteins play a variety of functions
