Scope of Biotechnology
Biotechnology may be as old as human civilization, but modern biotechnology is less than three decades old. Traditional biotechnology that led to the development of processes for producing products like vinegar, alcohol, and cheese was entirely empirical and bereft of any understanding of the mechanisms that led to the product. There was no possibility of deliberate design to produce a desired new product.
In modern biotechnology, we use the in depth understanding we have gained in the last five decades. A variety of functions are performed by living organisms to produce a desired new or old product. In the case of an established product, the biotechnological process is cheaper and better in many respects than the earlier processes. Modern biotechnology has been, infect, an historical imperative. Its emergence on the world scene was predicated at least four decades ago.
The term genetic engineering was coined independently in 1973 by the author of an article in the Guardian in the UK, and in a syndicated article by the present author in India.
