DNA: THE GENETIC MATERIAL The biologists of twentieth century realized that the genetic material must have certain characteristics. These charabteristics can explain the properties of life: 1: First, the genetic material must be able to code for the sequence of amino acids in proteins.
Genetics is divided into two parts: Classical and Mendelian genetics. (a) Classical Genetics The techniques and methodologies of genetics are called classical genetics. This genetics give rise to molecular biology. The discovery of the genetic codes and tools of cloning like restriction enzymes open
