Flashcards in Chapter 23: Virus taxonomy Deck (11):
What at the DNA viruses?
What are the RNA viruses?
What are the DS viruses
What are the positive stranded RNA viruses?
What are the negative stranded RNA viruses?
Where do most DNA viruses perform transcription and translation?
In the host cell nucleus
Where do most RNA viruses perform transcription, translation, and replication?
In the host cytoplasm
What are the three parts of DNA viral transcription?
early and late
Immediate early and early produce products that aid in further transcription and replication of gene products
Late occurs after replication has started and leads to the production of the proteins of the viral capsid
What is the difference between positive and negative RNA strands in virus gene production?
Positive act as mRNA and begin translation immediately.
Negative act as templates and produce a corresponding positive strand before translation.
What sets Retro viruses replication apart from other RNA viruses?
The strands of RNA work as a backbone that uses reverse transcriptase to produce a strand of DNA to insert into the hosts genome.
