Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

Gene is a segment of DNA that is responsible for synthesis of a particular type of protein. Gene that codes for a particular protein or enzyme is also called as cistron. In eukaryotes, these are monocistronic and the coding sequence is interrupted by short sequences which donot appear in the mature mRNA called as intron. The coding sequence involved in expression of the protein is termed exon.

Codon is the particular sequence of three N-bases that represents a specific amino acid found on the sequence of mRNA which is translated by the ribosomes to join amino acids in making long chain polypeptides.
