Document Summary

Eukaryotes: extrons and introns, removing intron fuses two extrons together, splicing, 5" cap, poly a tail. 5 types of rna mrna: only ones made into protein snorna: small nucleolar rna. 7. polymerase (dna/rna) always go 5" to 3" using 3" to 5" template. Initions: rna polymerase binds to promotor region of the gene (start of the gene, opens up dna, starts making rna in 5" to 3" direction. Elongation: rewinds as it unwinds, when promotor region free, another rna polymerase starts synthesizing rna. Termination: transcript released, new rna released, rna polymerase disassembles from gene multiple ribosomes attach to rna and make it into protein (translation) 10 sequence very at rich so unwinding starts there (tata box) Transcription start: rna polymerase bounds to tata box and opens up region. Termination: terminator stops transcription, two kinds, rho-independent, rho dependent (depended on rho - not covering in class)
