Document Summary
More than one virus type to affect certain hosts. The proteins are different, when mixed a new virus pops out of it: this is dangerous because our bodies don"t have antibodies to fight it (eg. h1n1 or. Exchange of genetic material to create a brand new virus. Unknown because of the fact that they can only manipulate host cells. In the nucleus (where the viral dna is kept) is where new viruses are made. Retroviruses: special class of +rna using reverse transcriptase to make new viruses grow, rna-dna-rna. Dsrna: once injected into the host cell it enters the nucleus, reproduces and then codes for. Naked inject dna into cell: derived from host and has viral proteins in it, like bacteriophages, genome (inner); viral capsid (hexagon), envelope (circle) Conservative: how many genotypes and phenotypes remain the same as evolution occurs. Community strain bacteria strain that one would find in standard population.
