Concept explainers
The hereditary material or a genetic potential of a living thing is referred to as genetic material. It is carried in the form of base sequences of DNA (deoxyribonucleic acid) as per the genetic code. The genetic code is made up of four bases, namely Adenine (A), Guanine (G), Thymine (T), and Cytosine (C).
Explanation of Solution
The genes are the basic unit of inheritance and are composed of DNA that is situated in the chromosomes. In a cell, the genetic information is stored in the form of DNA. It is a twisted, double-stranded helical molecule. The genetic information is transmitted to the progeny by the process of
