Detailed explanation-1: -DNA and RNA are both large biological polymers of nucleotides. Both DNA and RNA consist of sugar, nitrogenous bases, and a phosphate backbone. On both DNA & RNA Guanine & Cytosine are complementary to each other i.e. they form pair. Complementary base pairs are connected by hydrogen bonding.
Detailed explanation-2: -DNA and RNA molecules are polymers made up of long chains of nucleotides.
Detailed explanation-3: -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-4: -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-5: -Hence the correct answer is option C. The similarity between DNA and RNA is that both are Polymers of nucleotides.
