Document Summary
Dna and rna both are the types of nucleic acids (called so because they were isolated for the first time from the nuclei of pus cells by friedrich miescher and are acidic in nature). Dna is made of two polynucleotide chains that coil around each other to form the double helical structure while rna consists of only one polynucleotide chain that can bend and fold upon itself to give double helical character. Both these play an important role in central dogma that leads to the formation of proteins. Bases in dna are cytosine, guanine, thymine and adenine while in rna are cytosine, guanine, adenine and uracil thymine is jot found in rna.
