Unformatted text preview: sequences such as enhancers can affect transcription. adds NTPs at 3’ end of new polynucleotide until it encounters a termination signal at defined sequence and/or structure on the DNA template. the “pre-RNA” is “processed” into the mature RNA. In eucaryotes mRNA is transported to the cytoplasm. 15 BIO 1140 Unit 2-2: Transcription Transcription Overview Fig. 13-6, p. 290 (see also Fig 13-4 16 BIO 1140 Unit 2-2: Transcription DNA is the reddish part, where transciption starts. Transcription Overview (initiation) Fig. 13-6, p. 290 (see also Fig 13-4 17 TATA BOX: A-T rich sequence, the point at which RNA polymerase binds to start transcription and it helps to open up the helix. These are consensus sequences, so if you line them up and see the percentage of which one comes first and right (A-T), they are variants that exist in a population. Unwind the stransd and start transcribing and add RNA. May have a step loop struction and fold up, so you would need single binding proteins to keep the helix opened. It may...
