HIV Transmission Routes and Prevention — NEET Biology
📚 Practice ConceptWhat are the various routes by which transmission of human immuno-deficiency virus takes place?
Which of the following statements about retroviruses, specifically HIV, are correct? S1: Retroviruses possess a DNA genome that directly integrates into the host's nuclear DNA. S2: The enzyme reverse transcriptase is unique to retroviruses and is crucial for their replication cycle. S3: All retroviruses primarily infect helper T-lymphocytes, causing immunodeficiency. S4: The replication of HIV involves the formation of viral particles by the host cell's machinery after viral DNA integration. S5: Retroviruses like HIV are characterized by having an envelope around their genetic material.
