Answer:
DNA and RNA are nearly identical polymers of nucleotide, except for the base pairs. DNA contains thymine while the same is substituted with uracil in DNA is double stranded, while RNA is single stranded. RNA contains ribose as a sugar, while DNA contains deoxyribose. Also, three of the nitrogenous bases are the same in the two types adenine, cytosine, and guanine but DNA contains thymine while RNA contains uracil.
