Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
Answer:
A. Interphase
Explanation:
Interphase is when the DNA is copying itself. It is being prepared for the cell to divide and one of the key parts of mitosis is when the chromosomes duplicate, so to prepare for mitosis, the chromosomes must duplicate during interphase.
