BIOMOLECULES AND ENZYMES

Detailed explanation-1: -DNA & RNA are similar to each other as both are polymers of nucleotides. DNA is a polymer of deoxynucleotides and RNA is a polymer of ribonucleotides.

Detailed explanation-2: -Nucleotides simply refer to nitrogenous bases, pentose sugar together with the phosphate backbone. Both DNA and RNA have four nitrogenous bases each-three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

Detailed explanation-3: -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-4: -DNA and RNA both have four bases; two purines and two pyrimidines, in the nucleotide chains. The purines adenine and guanine and the pyrimidine cytosine are common to both DNA and RNA.
