Study Notes
Virus Structure
- Unlike cells, viruses have diverse genome structures, including double-stranded DNA (dsDNA), single-stranded DNA (ssDNA), double-stranded RNA (dsRNA), and single-stranded RNA (ssRNA).
- There are four types of viral genome structures: dsDNA, ssDNA, dsRNA, and ssRNA.
- Single-stranded RNA (ssRNA) viruses can be further classified into two categories: positive-sense (+ssRNA) and negative-sense (-ssRNA).
- Positive-sense (+ssRNA) viruses have a genome that can be directly translated into protein, similar to mRNA.
- Negative-sense (-ssRNA) viruses have a genome that must be transcribed into a complementary positive-sense RNA before it can be translated into protein.
