Hello!

RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.

RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.

Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information.
