Questions Related to introduction to genetic engineering and production of insulin

The proper definition of biotechnology is

commercial studies biotechnology: general introduction introduction to genetic engineering and production of insulin use of efficient and eco-friendly technology genetics of the future

  1. Use of living organisms and of substances obtained from them in industry

  2. Technology used to improve species of animals

  3. Modern technology used in biological laboratories

  4. Advanced technology used in biological warfare

Show answer
Correct Option: A
Explanation:
Biotechnology is the broad area of biology involving living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity, Art. 2). Depending on the tools and applications, it often overlaps with the (related) fields of molecular biology, bio-engineering, biomedical engineering, biomanufacturing, molecular engineering, etc. For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine. The term is largely believed to have been coined in 1919 by Hungarian engineer Károly Ereky. In the late 20th and early 21st centuries, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene techniques, applied immunology, and development of pharmaceutical therapies and diagnostic tests. 
So the correct option is 'use of living organisms and of substances obtained from them in industry'.

  2. Blue biotechnology

  3. Red biotechnology

  4. Grey biotechnology

Show answer
Correct Option: C
Explanation:
Red biotechnology(Bio-pharmaceutical) is a process that utilizes organisms to improve health care and help the body to fight diseases. It is a branch of modern biotechnology which is utilized in the field of medicine. Red biotechnology is not only limited to the pharmaceutical industry but also to the medical sector as it facilitates the alleviation of human suffering and enhances the quality of life. It has become tremendous use in clinical research and trials, gene therapy and in diagnostic of the gene. Genetic engineering, production, and development of various medicines to treat different life-threatening diseases, which is a part of the benefits of red biotechnology. Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures through genomic manipulation.

So, the correct option is 'Red biotechnology'.

  1. Genetic engineering

  2. Tissue culture

  3. Microbiology

  4. All of the above

Show answer
Correct Option: D
Explanation:

Biotechnology is the integration of natural science and organisms. Biotechnology involves pure biological sciences like animal cell culture, biochemistry, cell biology, embryology, genetics, microbiology, and molecular biology. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. 

The genes for antibiotic resistance are found in

commercial studies biotechnology: general introduction introduction to genetic engineering and production of insulin use of efficient and eco-friendly technology genetics of the future

  1. Chromosome

  2. Nucleus

  3. Cell wall

  4. Plasmid

Show answer
Correct Option: D
Explanation:

Antibiotic resistance plasmids are bacterial extrachromosomal elements that carry genes conferring resistance to one or more antibiotics. Resistance genes are commonly found on plasmids, which are small extrachromosomal elements commonly found in bacteria. Plasmids are commonly able to move from one bacterial cell to another by a mechanism known as conjugation, which involves cell‐to‐cell contact followed by transfer of a copy of plasmid DNA from a donor to a recipient. 

Therefore, the correct answer is option D.

The term biotechnology was given in 1917 by

commercial studies biotechnology: general introduction introduction to genetic engineering and production of insulin use of efficient and eco-friendly technology genetics of the future

  1. Arber

  2. Nathans

  3. Karl Erkey

  4. Kornberg

Show answer
Correct Option: C
Explanation:

Karl Ereky coined the word biotechnology in Hungary. This discovery and the naming was done in the year 1917. The term biotechnology is the branch of science which deals with the application of biological techniques for human welfare. It involves the modification of genes by the enzymatic action which leads to the production of some biological entity like antibodies, vaccines etc which benefits the mankind. 

Thus, the correct answer is option C. 

The typical machine for production of bioproducts through microbia is

  1. Sterilized glassware

  2. Microprojectile

  3. Autoclave

  4. Fermenter

Show answer
Correct Option: D
Explanation:

Fermenter is an apparatus that maintains optimal conditions for the growth of microorganisms, used in large-scale fermentation and in the commercial production of antibiotics and hormones. 

Therefore, the correct answer is option D.

Which one of the following approaches comes under the category of biotechnology?

commercial studies biotechnology: general introduction introduction to genetic engineering and production of insulin use of efficient and eco-friendly technology genetics of the future

Plants are more readily manipulated by genetic engineering than are animals because

commercial studies biotechnology: general introduction introduction to genetic engineering and production of insulin use of efficient and eco-friendly technology genetics of the future

  1. recombinant genes can be inserted into plant cells by microinjection

  2. a somatic plant cell can grow into a complete plant

  3. more vectors are available for transferring recombinant DNA into plant cells

  4. plant genes do not contain introns

Show answer
Correct Option: B
Explanation:

Plants have the ability to grow into a complete plant from a single cell. While animals are only produced by their species and reproduction. Hence, they are more readily manipulated by genetic engineering than an animal. 

So, the correct option is 'a somatic plant cell can grow into a complete plant'.

A genetically engineered micro - organism used successfully in remeditation of oil spills is a species of

  1. Pseudomonas

  2. Trichoderma

  3. Xanthomonas

  4. Bacillus

Show answer
Correct Option: A
Explanation:

Marine dwelling bacteria like Pseudomonas and fungi use the hydrocarbons as fuel and emit carbon dioxide as a result. The microbes break down the ring structures of the hydrocarbons in seaborne oil using enzymes and oxygen in the seawater. The end result is ancient oil turned into modern day bacterial biomass.
