There are numerous exceptions, howeverâsome viruses have genomes made of double-stranded RNA and other viruses have single-stranded DNA genomes, and, in some circumstances, nucleic acid structures with three or four strands can form.ach nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Nucleotides are also known as phosphate nucleotides.
