Viruses: Replication, Glycoproteins, DNA vs. RNA & Bacteriophages

how to viruses replicate ?

they hijack a cells host machinery

why do viruses need a host cell?

they can’t reproduce on their own

what do viral glycoproteins do?

help the viruses attach to host cell receptors

what’s the main idea of a glycoprotein?

glycoprotein is a = key; cell receptor = lock

what determines which cell a virus can infect?

the glycoproteins matching cell receptors

are viruses species specific?

yes

what is species jumping?

a virus infects a new host species

what does a virus use from the host to copy itself?

protein making machinery

do DNA viruses mutate quickly?

no they have better error checking

do RNA VIRUSES MUTATE QUICKLY?

yes

what is a bacteriophage?

virus that infects bacteria

what’s the host cell of a bacteriaphage

a bacterial cell

are bacteriophages common?

yes
