DNA or RNA RNA protein DNA
They pass through a wound. They bind to a membrane protein. They bind to the lipid bilayer. They puncture the cell wall.
HIV can infect cells other than CD4+ T cells. Mouse cells with CD4 in their membranes could be infected with HIV. Mouse cells with CD4 in their membranes could not be infected with HIV. Their close relatives, the SIVs, require a co-receptor.
It synthesizes proteins from mRNA. It synthesizes DNA from RNA. It synthesizes RNA from DNA. It synthesizes tRNAs from DNA.
ribosomes ATP nucleotides and amino acids all of the above
as they burst during budding as they integrate into the host chromosome during entry
cutting of long peptide chains into functional proteins assembly of particles folding of long peptide chains into functional proteins polymerization of amino acids into peptides
They have no protein fragments that can be recognized by a host cell. The vaccines tend to be unstable and deteriorate over time. New mutations constantly change viral proteins. So many protein fragments are represented that the immune system overreacts.
