Answer:
"One gene-one protein" hypothesis states that one gene codes for one protein while the "one gene-one polypeptide" hypothesis states that one gene codes for one polypeptide chain of a protein having more than one type of polypeptide chains.
Explanation:
Beadle and Tatum proposed the one gene-one protein concept to explain the one-to-one correspondence between genes and proteins. Accordingly, one gene carries information to encode one protein. Since enzymes are proteins with catalytic power, a gene encodes the information to produce a single enzyme.
The "one gene-one protein" concept was later modified into the "one gene-one polypeptide" hypothesis. According to the "one gene-one polypeptide" hypothesis, one protein may have more than one polypeptide chain. One gene carries the genetic information to encode one polypeptide. Therefore, a protein with more than one type of polypeptide chains will be encoded by more than one gene.
Genes are the hereditary units, which code the hereditary information and pass it from the parent to the offspring.
The one gene-one protein hypothesis states that one gene can code for one protein, such as the protein keratin is coded by the gene KRT1.
The one gene-one polypeptide hypothesis is also known as the enzyme hypothesis, in which the gene is responsible for the synthesis of the single polypeptide.
Enzyme hypothesis was given by Tatum, in which he explained that gene carries information to encode a protein. Enzymes have catalytic power and produce a single enzyme.
Thus, the hypothesis of one gene-one protein was modified into one gene-one polypeptide.
