We can distinguish a virus from others by the size shape and composition of its genome.

Other characteristics...

- They haven't got organelles.

- They haven't got metabolic autonomy, so they are not considered cells.

2: Intercellular

By themselves they are not able to do it because they lack the necessary molecular machinery.

There are a lot of types of viruses...
