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.
