|MoBio||Baltimore Classification of Viruses||Chapter 1|
The Baltimore classification is based on genetic contents and replication strategies of viruses. The genetic material in all types of cells is double-stranded DNA, but some viruses use RNA or single-stranded DNA to carry genetic information.
According to Baltimore classification, viruses are divided into the following seven classes:
where "ds" represents "double strand" and "ss" denotes "single strand".
