Pribnow box - Study guides, Class notes & Summaries

Pribnow box correct answers -interacts with a specific component of sigma part of RNA polymerase to line it up on DNA -located 10 bases before the start of transcription -consensus TATAAT Sigma factor correct answers -key to allowing RNA polymerase bind to promoter sequence -more than one sigma factor -turn on/off whole suits of genes -closer to particular sequence in promoter (consensus), the stronger the promoter -recognize Pribnow box and -35 region -35 region correct answers ~35 ...

Consensus sequences are described with IUPAC ambiguous nucleotide codes. What is a promoter? ~~> DNA sequence which RNA polymerase can bind to and transcribe the protein Prokaryotic promoters ~~> TATAAT -(10 region) 'Pribnow box' TTGACA - (-35 region) - two consensus sequences Prokaryotic RNA polymerase ~~> 1 RNA Polymerase makes all 3 kinds of RNA Composed of 5 subunits, four comprise the core enzyme What is the core enzyme? 2 | P a g e | © copyright 2024/2025 | Gr...

does DNA polymerase or RNA polymerase need a primer? - RNA RNA polymerase binds to an area called ____ - promoter what does the promoter do? - RNA polymerase attaches/initiates transcription Explain initiation in transcription - promoter binding occurs, RNA polymerase lands. DNA helix unwinds + enzyme initiates RNA synthesis @ start point on the template strand do eukaryotes or prokaryotes have a pribnow box? - prokaryotes
