The viral genome is integrated into the host genome by which of the following enzymes?
Correct answer: A. Integrase
- A. Integrase
- B. DNA incorporase
- C. Reverse transcriptase
- D. Protease
Explanation
The viral genome is integrated into the host genome by the integrase enzyme. Integrase is an enzyme that is found in retroviruses, such as HIV. It is responsible for inserting the viral DNA into the host cell's DNA. This allows the viral DNA to be replicated along with the host cell's DNA and to be passed on to daughter cells when the cell divides.

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.
