Terms Flashcards
The protein shell, or coat, that encloses the nucleic acid genome
Capsid
Morphologic units seen in the electron microscope on the surface of icosahedral virus particles
Capsomeres
A virus particle that is functionally deficient in some aspect of replication
Defective virus
A lipid-containing membrane that surrounds some
virus particles. It is acquired during viral maturation
by a budding process through a cellular membrane
Envelope
Virus-encoded glycoproteins that are exposed on the surface of the envelope
Peplomers
The protein-nucleic acid complex representing the packaged form of the viral genome.
Nucleocapsid
They are usually a collection of
more than one nonidentical protein
subunit. The structural unit is often
referred to as a ___________
Protomer
The complete virus particle
Virion
A single folded viral polypeptide chain
Subunit
The basic protein building blocks of the
coat. They are usually a collection of
more than one nonidentical protein
subunit.
