Document Summary
Announcements: quiz #3 is this friday, october 14th, discussion section out of class assignment is due next discussion - on moodle now, exam #3 is on tuesday, october 25th. Note: transcription factors are required to bring rna polymerase to the promoter. The next rna nucleotide added will be a. If top strand were template strand, o then rna polymerase would move from right to left (in 3" to 5" direction) An rna is in the middle of being produced from this piece of dna. The promoter sequence is off to the left. The promoter sequence is off to the right. Is the mrna transcript in between transcription and before leaving the nucleus: also called: o immature mrna o pre-mrna o nascent mrna. Rna processing: eukaryotic-specific, does not occur in prokaryotes. Introns: sequences in immature mrna that do get spliced out, don"t make it into the mature mrna transcript.
