The correct answer is option 2: Integrase. Integrase is an enzyme produced by HIV that plays a critical role in the viral replication cycle. It allows for the integration of HIV DNA into the host cell`s DNA. This process is essential for the virus to establish a permanent infection within the host cell.

To understand the role of Integrase, it is important to know that HIV is a retrovirus, meaning it uses RNA as its genetic material. Upon entering the host cell, HIV converts its RNA into DNA using another enzyme called reverse transcriptase. The resultant HIV DNA is then integrated into the host cell`s DNA with the help of Integrase. This integration allows the virus to remain within the host cell`s DNA and be replicated along with the host`s genetic material.

In summary, Integrase is responsible for incorporating HIV DNA into the host cell`s DNA, ensuring the persistence and reproduction of the virus within the infected individual.
