Baltimore Classification System

These flashcards cover essential aspects of the Baltimore Classification System, including the types of genomes and their transcription needs.

What does the Baltimore Classification System categorize?

Viruses based on how they produce mRNA.

Group I in the Baltimore Classification System is characterized by which type of genome?

Double-stranded DNA (dsDNA).

What must single-stranded DNA (Group II) do before transcription?

Be converted to double-stranded DNA (dsDNA).

Which group of the Baltimore Classification requires viral RNA-dependent RNA polymerase?

Group III (dsRNA).

Define positive-sense RNA as described in the Baltimore Classification System.

Positive-sense RNA; can be directly translated into protein.

What is the requirement for negative-sense RNA before translation according to the Baltimore Classification?

It must be transcribed into positive-sense RNA before translation.

What is the genome type for Group IV in the Baltimore Classification?

Positive-sense RNA.

What type of RNA does Group V represent in the Baltimore Classification?

Negative-sense RNA.
