The structure of nucleic acids, DNA and RNA, differ in that
RNA's backbone is made up of phosphates, while DNA's backbone is made up of nitrates.
RNA contains only three different nucleotides, while DNA contains four different nucleotides.
DNA's nucleotide sequence is single stranded, while RNA's nucleotide sequence is double stranded.
DNA contains a nucleotide with thymine, while RNA contains a nucleotide with uracil.
