In a retrovirus - Study guides, Class notes & Summaries

HIV (Retrovirus) Life Cycle A retrovirus such as human immunodeficiency virus (HIV) uses reverse transcriptase to copy its RNA into double-stranded DNA. The DNA then enters the nucleus to recombine in the host genome, where a host RNA polymerase generates viral mRNA and viral genomic RNA. The viral mRNA enters the cytoplasm for translation. Viral coat proteins are transported by the endoplasmic reticulum to the cell membrane, where virions assemble and bud out. gp120, CD4 HIV viruses con...
