saves genetic material; same shape helps to support defective capsomeres |
|
|
Term
|
Definition
some capsids have as a thick outer cloak made out of pieces of cell membrane collected when the virus buds |
|
|

If HIV were the size of a softball... |
|
Definition
the host white blood cell would be the size of a classroom |
|
|
Term
|
Definition
when cell is invaded the cell's genetic code is copied into viral mRNA. When the mRNA travels to the ribosomes it directs the cell to create proteins for the virus' replication |

|
Definition
When virus infects a cell,it releases its RNA that attaches to ribsomes to be madeinto virus proteins |
|
|
Term
|
Definition
uses reverse transcriptase which converts viral RNA to viral DNA and viral DNA puts itself into host protein |
