A wine maker and a molecular biologist, who has developed a recombinant vaccine, both claim themselves to be biotechnologist. Who is right in your opinion?
Both are right, because biotechnology is a very wide area. It deals with techniques of using a natural organism or its parts as well as genetically modified organism to produce products and processes useful for the mankind.
A wine maker employs a strain of yeast to produce wine by fermentation (a natural phenomenon), while the molecular biologist has cloned gene for the antigen (that is used as vaccine) in an organism, which allows the production of the antigen in large amount.
