DNA is a double helix model with two types of nitrogenous base. They are purines and pyrimidines. The two types of purines are: Adenine and Guanine. The two types of pyrimidine are: cytosine and thymine. The hydrogen bond formed is between Adenine and thymine. Guanine is bonded with cytosine. The first genetic material was RNA. There are three types of RNA. They are: m – RNA, t – RNA, r – RNA. These three RNA’s are required for the synthesis of protein in the cell. m -RNA is also called messenger RNA. t- RNA is also called transfer RNA. and r – RNA is also called ribosomal RNA. This is a brief on Molecular Basis of Inheritance.
