In 1948, Beadle and Tatum proposed that a gene controls the synthesis of one enzyme. But, many enzymes, as well as the haemoglobins were shown to consist of two or more different polypeptide chains and each polypeptide was found to be the product of a separate gene. Tryptophan synthetase of E. coli, for example, contains an a - polypeptide, the product of the trp A gene and a 3 - polypeptide, the product of the £ gene. It was necessary, therefore, to change the concept of one gene-one enzyme to one gene-one polypeptide.

Assertion and Reason:
- Assertion: The concept of one gene-one enzyme was changed to one gene-one polypeptide.
- Reason: Each enzyme may consist of two or more different polypeptides.
Explanation:
The concept of "one gene-one enzyme" was initially proposed by Beadle and Tatum in the 1940s. They conducted experiments on the bread mold Neurospora crassa and discovered that each mutant strain of the mold was defective in a specific enzyme. They concluded that each gene is responsible for producing a specific enzyme. However, this concept was later modified to "one gene-one polypeptide" based on further research.
Why the Assertion is True:
The assertion is true because it reflects the modification of the original concept proposed by Beadle and Tatum. Instead of stating that each gene codes for a specific enzyme, the modified concept states that each gene codes for a specific polypeptide. This modification was necessary because not all gene products are enzymes. Some gene products are structural proteins or play regulatory roles in cellular processes.
Why the Reason is True:
The reason is true because it highlights the fact that enzymes can be composed of multiple polypeptides. Enzymes are complex proteins that catalyze biochemical reactions in living organisms. Many enzymes are composed of multiple subunits, where each subunit is a polypeptide chain encoded by a separate gene. These subunits come together to form the functional enzyme.
Explanation of the Relationship:
The reason serves as a correct explanation for the assertion. The concept of "one gene-one polypeptide" was introduced because it acknowledges that some enzymes are composed of two or more different polypeptides. Therefore, the modified concept accommodates the complex nature of enzymes and the presence of multiple polypeptides in their structure.
Conclusion:
In conclusion, both the assertion and reason are true, and the reason is the correct explanation of the assertion. The concept of "one gene-one enzyme" was modified to "one gene-one polypeptide" to account for the fact that enzymes can be composed of multiple polypeptides. This modification allows for a more comprehensive understanding of gene expression and protein synthesis.
