Answer:
Viruses and bacteria have a very specific way of organizing their own genetic material inside themselves.
Step-by-step explanation:
On viruses, this can vary a little bit, but most of them will have their genetic material not confinated in a nucleus, but so, spread along all of the cytoplasm. This can be because of very different reasons, and the bacteria have the same thing here, they too have their genetic material spread all across their cytoplasm.
Instead of that, eukaryotes have something that the scientists call the nucleus. This nucleus contains all the DNA a cell needs to produce the proteins for the body, but remember, the protein making process happens inside and out of the nucleus.
