Weekly Quiz Competition

Question 1
1 / -0

In which field application of biotechnology occurs?

A
Biomedicine

B
Agriculture

C
Environmental field

D
All of the above

Solution

Biotechnology is an interdisciplinary science that covers biology, mathematics, physics, chemistry and engineering. Various technologies are applied together to living cells in order to produce or improve a product for the well being of living organisms. Its application occurs in various fields including biomedicine to introduce new medicine in order to ease suffering and prolong life, agriculture to improve crop yield, environmental field to solve environmental problems, in food industry to improve and increase production of nutritious food, etc
Thus, the correct answer is option D.
Question 2
1 / -0

The resistant variety of rice to bacterial blight is

A
Jaya

B
TMK-6

C
IR-20

D
IR-8
Solution
- Xanthomonas campestris causes bacterial blight of rice which is one of the most important diseases of rice in most of the rice-growing countries. Bacterial blight of rice has high epidemic potential and is destructive to high-yielding cultivars in both temperate and tropical regions especially in Asia.
- IR8 is a high-yielding semi-dwarf rice variety developed by the International Rice Research Institute (IRRI) in the early 1960s. It is the resistant variety of rice to bacterial blight.
So, the correct answer is 'IR-8'
Question 3
1 / -0

Biopiracy is related to

A
Bioresearches

B
Traditional knowledge

C
Biomolecules and genes discovered

D
All of the above

Solution

The commercial development of biological compounds or genetic sequences by a technologically advanced country or organization without obtaining consent from or providing fair compensation to the people or nations in whose territory the materials were discovered is known as biopiracy.
Question 4
1 / -0

Which of the following correctly defines a transgenic animal

A
An animal which has foreign DNA and RNA in some of its cells because of an injection of DNA and RNA into the nucleus of the zygote from which it is developed

B
An animal which has foreign DNA in all its cells because of an injection of DNA into the nucleus of the zygote from which it is developed

C
An animal which has foreign DNA in some of its cells because of an injection of DNA into the nuclei of some of the cells of the blastocyst

D
An animal which has foreign DNA in.all its cells because of an injection of DNA into the nuclei of some of the cells in adulthood
Question 5
1 / -0

Genetic engineering has been successfully used for producing

A
Animals like bulls for farm work as they have super power

B
Transgenic mice for testing safety of polio vaccine before use in humans

C
Transgenic models for studying new treatments for certain cardiac diseases

D
Transgenic Cow-Rosie which produces high fat milk for making ghee

Solution

Genetic engineering has been successfully used for producing transgenic mice. Many transgenic mice are designed to increase our understanding of how genes contribute to development of diseases. Transgenic mice are being developed for use in testing the safety of vaccines before they are used in human beings. For example transgenic mice are being used to test the safety of polio vaccine. Hence option B is correct.
Question 6
1 / -0

Which transgenic animal have been given human genes for organ transplantation into human without risk of rejection

A
Cow

B
Sheep

C
Goat

D
Pig
Question 7
1 / -0

Plants in comparison to animals are more rapidly manipulated by genetic engineering. Select out the most probable reason for this.

A
Totipotency shown by plant cells.

B
Single somatic cell can regenerate a whole plant body.

C
Genetic engineering is supplemented with plant tissue culture techniques.

D
All of the above
Solution
- Genetic engineering is the manipulation of an organism's genetic structure using biotechnological methods.
- Plants can easily undergo genetic modifications as compared to animals because plant cells can differentiate into any cell types as compared to animals cells (totipotency).
- Their viability can easily be maintained in an artificial culture medium during tissue culture, where a single somatic cell can regenerate into a whole plant and tissue culture technology is advanced enough to enable and enhance these methods.
So, the correct answer is 'All of the above'.
Question 8
1 / -0

Abnormal gene is replaced by normal genes through

A
Gene therapy

B
Medicines

C
Cloning

D
Radiation

Solution

Gene therapy is the use of nucleic acid polymers as a drug to treat disease, where they correct genetic abnormalities. The most common form of gene therapy involves using DNA that encodes a functional, therapeutic gene to replace a mutated gene. In gene therapy, the nucleic acid molecule is packaged within a "vector", which is used to get the molecule inside cells within the body.
Thus, option A is correct.
Question 9
1 / -0

The transgenic animals are those which have __________________.

A
Foreign DNA in some of its cells

B
Foreign DNA in all its cells

C
Foreign DNA and RNA in some of its cells

D
Foreign DNA and RNA in all its cells
Solution
Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome.
Such animals are most commonly created by the micro-injection of DNA into the pronuclei of a fertilized egg, which is subsequently implanted into the oviduct of a surrogate mother.
This zygote will now be developed to form an embryo and later a complete individual, and all the cells in that individual will have that foreign DNA.
So, the correct answer is 'Foreign DNA in all its cells'
Question 10
1 / -0

The illegal and unlawful development of biomaterials without payment to the inhabitants of their origin is called

A
Biopatent

B
Biotechnology

C
Bio-war

D
Biopiracy

Solution

Biopiracy is exploitation of indigenous knowledge of nature, biological products and its use without permission from and with little or no compensation to the indigenous people themselves.
So, the correct answer is 'Biopiracy'
