The enzyme "reverse transcriptase" present in HIV virus is:
Correct answer: A. 50 molecules per virion
- A. 50 molecules per virion
- B. 40 molecules per virion
- C. 30 molecules per virion
- D. 20 molecules per virion
Explanation
In summary, the specific number of reverse transcriptase molecules per HIV virion can vary due to factors like viral strain and infection stage. While options from 20 to 50 molecules per virion are feasible, the actual quantity is not definitively established. Option A, with 50 molecules per virion, is considered the most suitable answer here because it falls within the possible range of values despite variability in the actual count.
