Bacteriophage - answer✔a virus that infects bacterial cells
capsid - answer✔the protein shell that surrounds the genome of a virus particle
capsomere - answer✔the subunit of a viral capsid
concatemer - answer✔two or more linear nucleic acid molecules joined covalently in tandem
early protein - answer✔a protein synthesized soon after virus infection and before replication of
the virus genome
enveloped - answer✔in reference to a virus, having a lipoprotein membrane surrounding the
virion
host cell - answer✔a cell inside which a virus replicates
late protein - answer✔a protein, typically a structural protein, synthesized late in virus infection
lysogen - answer✔a bacterium containing a prophage
lysogeny - answer✔a state in which the viral genome is replicated in step with the genome of the
host
lytic pathway - answer✔the type of virus infection that leads to virus replication and destruction
of the host cell
middle protein - answer✔a protein with either a structural or catalytic function synthesized after
the early proteins in a virus infection
nucleocapsid - answer✔the complex of nucleic acid and capsid (shell) proteins of a virus
plaque - answer✔a zone of lysis or growth inhibition caused by virus infection of a bacterial
lawn or other culture of sensitive host cells
