In case of HIV, only_ can infect host cells.
Correct answer: B. Double stranded DNA
- A. Single stranded RNA
- B. Double stranded DNA
- C. Double stranded RNA
- D. Single stranded DNA
Explanation
While the original genetic material of HIV is single-stranded RNA, the virus undergoes a process called reverse transcription. During this process, the single-stranded RNA is converted into a complementary single-stranded DNA (cDNA) molecule. This cDNA is then integrated into the host cell's genome, forming a double-stranded DNA structure that can infect host cells.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
