WebANSWERS to Questions from Part Three . Answers, Chapter 10. Transcription: RNA polymerases . 10.1 The sigma factor (s) causes RNA polymerase to bind to the correct sites on DNA to initiate transcription (i.e. promoters). s destabilizes the complex between core polymerase and non-promoter DNA and decreases the amount of time it is bound. It … Web1. The direction indicated by A, is the correct direction of RNA polymerase movement. 2. If C and D are both pointing to the first ribosome in the chain, then ribosome C is carrying a longerpolypeptide chain. 3. If E is pointing to mRNA, then it is pointing to the 5’end of the mRNA 4.
