Both contain uracil.

Detailed explanation-1: -One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach. Because of the phosphate group, this backbone is negatively charged-a quality many genetic techniques appreciate and exploit.
Detailed explanation-2: -Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.
Detailed explanation-3: -Both the molecules of DNA and RNA are formed of monomers known as nucleotides. Both these molecules possess four nitrogenous bases. Both the molecules of DNA and RNA exhibit a phosphate backbone to which attachment of bases takes place.
Detailed explanation-4: -An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).
