Document Summary
Transcription: synthesizes new strand 5" to 3", reads template strand 3" to 5", upstream is to the left, about 35 base pairs upstream is rich in a and t (prokaryotic promoter, prokaryotic rna polymerase can initiate transcription on their own, a/t rich sequence is most easily opened because they only have 2 hydrogen bonds, eukaryotic promoter is located about 30bp upstream, called tata box, transcription termination in eukaryotic genes involves endonuclease cleavage just upstream of gu rich sequence, this is followed by addition of poly(a) tail, mrna are intermediate between dna and protein.
