B. An obligate intracellular parasite with either DNA or RNA as its genomic material
C. A smelt (20 to 250 nm) genome covered by a lipid envelope
D. A self replicating protein found in the brain ofsome animals
E. An obligate intracellular parasite that upon infection always results in disease 32) The general steps in the life welt: of all viruses are
A. entry of viral genome, replication, gene expression, capsid assembly, leiease X.
B. attachment to the host, entry ofviral genome, gene expression, capsid assembly, X
release c. anaehmentto the host, entry of viral genome, gene Expression, ratiﬁcation, capsid assembly, cell lysis, release
