Term
|
Definition
| outer protein layer that surrounds the genetic material of a virus |
|
|
Term
|
Definition
| viral replication process in which genetic material of the virus enters the host cell's cytoplasm, the cell replicates the viral DNA or RNA, and the host cell is instructed to manufacture captids and assemble new viral particles which then leave the cell |
