ABSTRACT
In order to understand how di erent monomers recognize each other, let us take the example of deoxyribonucleic acid (DNA), which is located in the nucleus of a cell. e DNA is made up of the following bases adenine (A), guanine (G), cytosine (C), and thymine (T), which are held together by two chemical bonds-one is a covalent or phosphodiester bond and the other is a hydrogen bond. Each of these bases is attached to a sugar and a phosphate molecule. Together, a base with a sugar and a phosphate molecule forms the nucleotide, which is a monomer. e hydrogen bond helps the DNA to maintain its stability.
