bacteriaphage: capsid stays on outside of host cell, DNA injected into cell
capsid-protein shell surrounding viral genome
Viruses of eukaryotic cells: virus engulfed by host cell; capsid broken down by our enzymes, freeing genetic material of virus
(viral genomes can be DNA or RNA)
2) viral genes expressed (ex: genetic material of virus transcribed and translated into protein)
by host cell cell ribosonesetic and viral genetic material copied by host cell enzymes (DNA polymerase)
