Pan-vertebrate comparative genomics unmasks retrovirus ... - PNAS
: Finally, a protease enzyme cleaves the viral proteins into their functional forms, maturing the virus so it can infect new cells. Human Health and Diseases Retrovirus
: The virus attaches to specific receptors on a host cell (like CD4 receptors in the case of HIV) and fuses with the membrane, releasing its RNA and enzymes into the cytoplasm. Pan-vertebrate comparative genomics unmasks retrovirus
Retroviruses are a unique family of viruses that have fundamentally changed our understanding of genetics, evolution, and medicine. Unlike most living organisms that store genetic information as DNA, retroviruses carry their genetic blueprint as . Their name refers to their "backward" replication process: they use a specialized enzyme called reverse transcriptase to convert their RNA into DNA once they infect a host cell. The Replication Cycle: Rewriting the Host’s Code Retroviruses are a unique family of viruses that
