All enzymes are present in HIV except:
Correct answer: D. Lysozyme
- A. Reverse transcriptase
- B. Integrase
- C. Protease
- D. Lysozyme
Explanation
HIV contains reverse transcriptase, integrase, and protease because these enzymes are essential for its replication cycle: reverse transcriptase converts viral RNA into DNA, integrase inserts this DNA into the host genome, and protease processes viral proteins for assembly of new viruses. Lysozyme, on the other hand, is an enzyme that breaks down bacterial cell walls, which is unnecessary for HIV since it infects human cells, not bacteria.

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.
