General Characteristics of Viruses

Capsid  -  The protein coat that surround the genetic material of a virus.
Envelope  -  A membranous covering found on some virus capsids that allows the virus to enter a host cell by fusing with the host's cell membrane.
Enzymes  -  Proteins that act as catalysts for chemical reactions.
Genes  -  A unit of genetic material containing the information needed to produce and regulate a single protein.
Lysogenic  -  The phase found in some viruses in which the virus's genetic material becomes incorporated into the host cell and no new viruses are produced. Compare with lytic.
Lytic  -  In viruses with a lysogenic phase, the opposing phase in which virus replication takes place.
