#Unit 3. Fundamental Processes
Three defined steps in a transcription cycle; choose correct one
|
1a. Closed complex |
In this form, the DNA remains double-stranded, and the enzyme is bound to one face of the helix. I |
|
1b. Open complex |
In which the DNA strands separate over a distance of 13 bp around the start site to form the transcription bubble. In the next stage of initiation, |
|
2. Promoter escape |
Incorporation of the first 10 or so ribonucleotides is a rather inefficient process, and at that stage, the enzyme often releases short transcripts and then begins synthesis again |
|
3. Initial transcribing complex. |
Once an enzyme makes a transcript longer than 10 nucleotides, it is said to have |
