Viruses are small and fairly simple organisms that are considered living beings by some authors and not alive by others. To get an idea of the size of these organisms, the smallest virus on record is only 20 nm in diameter, so it is smaller than a ribosome. Viruses are mainly known to cause various diseases and are considered obligatory intracellular parasites.
The genome of viruses is very differentiated, existing organisms with DNA or RNA for this reason, we can conclude that viral chromosomes exist in a variety of conformations and can be made up of DNA or RNA.
