HIV viruses does not follow central dogma. Central dogma is one way flow of information from DNA to mRNA and then to protein.

1. DNA → transcription → mRNA → translation → Protein
2. DNA → reverse transcription → Protein
3. DNA → translation → mRNA → Protein
4. DNA → transcription → Protein

Correct answer: DNA → reverse transcription → Protein

Solution

HIV is a retrovirus, and retroviruses use reverse transcriptase to copy RNA into DNA, which is the opposite of the usual central dogma direction. That backward information flow is why the correct choice includes reverse transcription.
