Textbook Chapter 6 Microviruses

Question 1

overlapping reading frames in genomes of microviruses do what?

Answer 1

maximize genetic coding capacity

Question 2

single stranded DNA viruses must produce a double stranded DNA before what?

Answer 2

host cell RNA polymerase can transcribe viral genes

Question 3

replication of a microvirus DNA occurs on a what?

Answer 3

double stranded DNA intermediate via a rolling circle mechanism

Question 4

synthesis of single stranded microvirus genomes DNA takes place when?

Answer 4

concurrently with DNA packaging

Question 5

Scaffolding proteins do what?

Answer 5

mediate capsid assembly by lowering thermodynamic barriers and ensuring the temporal nature and fidelity of the assembly pathway

Question 6

what kind of viruses may be evolutionary related?

Answer 6

small, icosahedral, single stranded circular DNA viruses
