DNA, along with RNA and proteins, is one of the three major macromolecules that are essential for life. DNA and RNA share many characteristics. They are both composed of nucleotide monomers and are read in the 5'-to-3' direction. They also share the same complementary base pairs, except RNA uses uracil in place of thymine; both contain adenine. The chemical structure of RNA is very similar to that of DNA: each nucleotide consists of a nucleobase a ribose sugar, and a phosphate group. Unlike DNA, most RNA molecules are single-stranded and can adopt very complex three-dimensional structures. The presentation will provide further insight on the topic.
