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.

ethanol into glucose and water.
Explanation:
In patient-centered care, all healthcare decisions and quality measurements are driven by the individual's specific health needs and desired health outcomes. The patient is always a partner to the health care provider, thus following these eight principles.

Mrs Zahari is considered to receive effective, safe and patient-centered care if she is treated not only on the clinical perspective but also on the emotional, mental, social, spiritual and financial perspective and the health care provider follows the eight principles of patient-centered care.
The cell would shrivel. This is due to the fact that it would lose water to the surrounding 2% sugar solution through osmosis. The surrounding sugar solution is more concentrated hence hypertonic compared to the cell solution of 1%. Water, in osmosis, moves from a hypotonic solution to a hypertonic solution, through a semipermiable, until an isotonic balance is achieved.
