The Baltimore classification of viruses is based within the mechanism of mRNA creation. Viruses have to make mRNAs from their genomes to make proteins and replicate themselves, but distinct mechanisms are applied to realize this in Each individual virus family members.
Some bacteriophages are termed "temperate" simply because they induce latent infections and don't right away destroy their host cells. Rather, their DNA is incorporated With all the host cell's as a prophage.
