All enzymes are present in HIV except:

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.
