One gene-one enzyme hypothesis was postulated by:
- R.Franklin
- Hershey and Chase
- A.Garrod
- Beadle and Tatum
The Correct Option is D
Solution and Explanation
Beadle and Tatum conducted seminal experiments using Neurospora crassa to demonstrate that in a multi-step biochemical pathway, distinct enzymes control each step, and each of these enzymes is determined by a specific gene. This concept is referred to as the “one gene, one enzyme hypothesis”.
So, the correct option is (D): Beadle and Tatum

Biotechnology
Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Principles of Biotechnology:
Among many, the two core techniques that entitled the birth of modern biotechnology are :
- Genetic Engineering is one of the methods of direct modifications of an organism's genome (i.e., DNA and RNA). It requires the introduction of new genes into host species to escalate function or trait, hence altering the host organism's phenotype.
- Bioprocess Engineering is one of the methods of maintaining sterile conditions to facilitate the growth of large quantities of desired microbes and other eukaryotic cells for the development of new or modified biotechnological products such as enzymes, vaccines, antibiotics, and other biotechnological products.
