a) 1970
b) 1980
c) 1990
d) 2000
View Answer
Explanation: The U.S. Supreme court ruled in 1980 in favour of patented micro-organisms. This was the case of Diamond versus Chakrabarty. This verdict opened a new commercial avenue for fermentation.
4. The interaction between the science of biology and technology is called _______
a) Biotechnology
b) Micro-biology
c) Bio-science
d) Forensics
View Answer
Explanation: Fermentation, antibiotic production, baking and brewing are included in old biotechnology, whereas techniques related with cell culture, fusion, bioprocessing, genetic engineering etc. were named as new biotechnology.
5. Who defined biotechnology as the application of biological organisms, system or processes to manufacturing and service industries?
a) Japanese biotechnologists
b) British biotechnologists
c) US National Science Foundation
d) European Federation of Biotechnology
View Answer
Explanation: Biotechnology is defined as the integrated use of biochemistry and microbiology. This is defined by European Federation of Biotechnology. This helps in achieving technological application of the micro-organisms.
