capsid, enzyme, envelope

A Virus is always made up of: OPTIONS: capsid, capsule, envelope, enzymes, genome

capsid, genome

select the ways that describe how an animal virus can enter or penetrate a host cell.

endocytosis, membrane fusion

a virulent virus has a lysogenic relationship with the host cell while a temperate virus has a lyric infection relationship with the host cell. T/F

false

once injected into a host cell, the genome of a virus with negative sense rna can be directly read and translated into protein by the host cell ribosomes. T/F

false

uncoating is a necessary step for bacteriophage, but not animal viruses T/F

false

which two steps in bacteriophage replication use the enzyme lysozyme

penetration, release

a retrovirus uses a rna dependent dna polymerade called what to make dna from an rna template?

reverse transcriptase

which step of replication differs the most between an animal rna and an animal dna virus?

synthesis

viruses have a genome made up of rna or dna, but not both rna and dna T/F?

true

if an organism had a genome (dna) made up of 60000 base pairs, and you know that there are 18000 Cytosine, how many Thymine are there?

42000
