The genes and polypeptides it codes are said are to be collinear. Explain?

Text Solution

Verified by Experts

Collinearity of Gene (DNA) and Polypeptide structure. Charles Yonofsky and his associates have provided that gene and the polypeptide it codes for, both are collinear. The nucleotides are arranged in the genes (DNA) in a linear segment and similarly amino acids are linked with each other by peptide bonds in a polypeptide strand. The sequence of amino acid in the polypeptide chain corresponds to the sequence of nitrogen bases in the gene that codes for it.
