6152043007	Capsid	The protein shell that encloses the viral genome	0
6152045122	Viral envelopes	Membranes that surround the capsids of some viruses and are derived from the host's cell membranes	1
6152060560	Bacteriophages	Viruses that infect bacteria	2
6152065667	Host range	A limited number of host cells that a virus can infect	3
6152069886	Lytic cycle	A phage reproductive cycle that culminates in the death of the host cell	4
6152076239	Virulent phage	A phage that reproduces only by the lytic cycle	5
