This set of Basic Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Nature of Biotechnology”.
1. What are the two disciplines that clarify the understanding of chemical and biochemical processes of biological systems?
a) Chemical Engineering and Biochemistry
b) Equilibrium and Thermodynamics
c) Fluid Mechanics and Thermodynamics
d) Microbiology and Bioinformatics
View Answer
Explanation: Chemical engineering and biochemistry are two well recognised examples. These are disciplines that have done much to clarify our understanding of chemical processes and the biochemical bases of biological systems. Biochemistry is even more closely linked to the biological systems.
2. Which term describes the quantitative extension of approaches to problems within a specific area?
a) Interdisciplinary
b) Intradisciplinary
c) Multidisciplinary
d) Domain
View Answer
Explanation: The term multidisciplinary describes a quantitative extension of approaches to problems that commonly occur within a given area. It involves the marshalling of concepts. It also involves methodologies from a number of separate disciplines and applying them to a specific problem in another area.
3. In the diagram below, which represents a biotechnological process, what is process [A]?
a) Sterilisation
b) Inoculation
c) Cultivation
d) Harvesting
View Answer
Explanation: In any biotechnological process, sterilisation is succeeded by raw material selection and preparation. The predecessor of bioreactor step is always sterilisation step. The successor of pre-treatment is always sterilization.
4. Which among the following has highest value in World Markets for Biological Products?
a) Alcoholic beverages
b) Cheese
c) Antibiotics
d) Penicillin
View Answer
Explanation: Alcoholic beverages have highest value in the World Markets for Biological Products. It has a net worth of 23000 US$ millions. This is according to census 1981.
5. Prior to 1982, Insulin for diabetes was derived from which source?
a) Pig Pancreas
b) Lion Pancreas
c) Sheep Pancreas
d) Goat Pancreas
View Answer
Explanation: Prior to l982, insulin for diabetics was derived from beef and pork pancreases. The gene for human insulin was then isolated and cloned into microorganisms. This was then mass-produced by fermentation.
6. Which Technology is used to transfer a particular gene from one organism to another called?
a) Nano technology
b) R-DNA technology
c) Marine technology
d) Water technology
View Answer
Explanation: R-DNA technology or Recombinant-DNA technology is used to transfer a particular gene from any organism to another organism. The organisms can include microorganisms, plants or animals. Animal usage has different set of ethical rules.
7. The developments of biotechnology are proceeding at the rate similar to that of microelectronics in mid-1970s.
a) True
b) False
View Answer
Explanation: Developments of biotechnology are proceeding at the rate similar to that of microelectronics in mid-1970s. Although the analogy is that, any expectations that biotechnology will develop commercially at the same spectacular rate should be tempered with considerable caution. This analogy must be considered before investing.
8. The growth in awareness of modern biotechnology parallels the serious worldwide changes in the economic climate arising from the escalation of oil prices since which year?
a) 1971
b) 1972
c) 1973
d) 1974
View Answer
Explanation: It is because there is a growing realisation that fossil fuels and other non-renewable resources will one day be limited in supply. It is when biotechnology could perhaps be introduced. Bioenergy is a cheaper alternative source for energy.
9. Current recession in western world towards the use of chemical and engineering sections is a contributory factor to growing interest in biotechnology.
a) True
b) False
View Answer
Explanation: In the western world, there is a recession towards the use of chemical processes. This results in preferences to biotechnological processes. It is because of the increased costs of chemical and engineering sections.
10. Which region must hold a high future in biomass production?
a) Wetlands
b) Plains
c) Evergreen regions
d) Tropical regions
View Answer
Explanation: The tropics have climatic conditions favouring rapid biomass production. They also possess high future potential in bio based productions. So tropics hold a high future in biomass production.
11. Which is the first pharmaceutical company to produce human insulin using recombinant DNA technology?
a) Eli Lilly
b) Biocon
c) Abyss Biotech
d) Vyome Biosciences
View Answer
Explanation: Eli Lilly is a pharmaceutical company. It first produced human insulin using R-DNA technology. It is currently the largest manufacturer of psychiatric drugs.
12. Name the first approved biosimilar insulin product in the US.
a) Dolophine
b) Prozac
c) Humulin
d) Basaglar
View Answer
Explanation: Basaglar, is the first approved biosimilar insulin product. It is marketed under the name Lantus and is a long acting basal insulin analogue. It has microcrystals that slowly release insulin.
