Question

1) Procaryotic transcription has three steps, name them and 2) A is the DNA sequence recognized by the RNA polymerase 3) This protein is needed by the bacterial RNA polymerase to increases its affinity for the DNA sequence identified in #2: 4) T/F-_ An RNA polymerase needs a primer to transcribe. 5) Initially, the RNA polymerase complex is in the closed complex where the DNA is still double- stranded. The next step is the separation lof the DNA double helix. This is called the complex. 6) The structure of the RNA polymerase complex resembles that of a 7) Name one mechanism of RNA proofreading: 8) Name the molecular technique used to identify binding of RNA polymerase to its promoters 9) These DNA sequences trigger the elongating RNA polymerase to dissociate from the DNA and release the RNA chain: 10) This process in #9 can be stimulated by the protein known as
