Terms Flashcards
(10 cards)
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.
