Question 1
1 / -0.25

What is the term used to refer to the use of bio-resources by multinational companies and other organizations without proper authorization from the countries and people concerned without contemporary payment is?

A
Bioethics

B
Bioremediation

C
Biodegradation

D
Bio-piracy

Solution

The term used to refer to the use of bio-resources by multinational companies and other organizations without proper authorization from the countries and people concerned without contemporary payment is Bio-piracy. It happens when biological resources are taken or exploited without official sanction.
Question 2
1 / -0.25

Seeds of golden rice are yellow in colour because

A
It has vitamin E encoding gene

B
Provitamin A is produced in the entire grain

C
It has vitamin B encoding gene

D
It is a biproduct of 3 genes

Solution

The seeds of golden rice are yellow in colour due to presence of provitamin A in entire gene. This rice is natural source of vitamin A along with starch and proteins.
Question 3
1 / -0.25

Flavr Savr tomato is produced______.

A
for pest resistance

B
to enhance self-life of fruits

C
for frost resistance

D
for herbicide tolerance

Solution

Flavr Savr tomato has thick fruit coat that enhance the self-life of the fruits and do not get spoiled soon. Common Indian tomato have thin coat and easily get destroyed during transportation and handling.
Question 4
1 / -0.25

GM Arabidopsis produces dsRNA to

A
To produce more protein product

B
To stop transcription

C
Knock out specific parasitic genes in the nematode

D
To make DNA non functional

Solution

Genetically modified (GM) Arabidopsis produces double stranded RNA to knock out specific parasitic genes in the nematode that harms the crops by silencing specific mRNA of nematodes.
Question 5
1 / -0.25

Cry genes introduced in a plant will not be affective against

A
lepidoptera

B
hymenoptera

C
coleoptera

D
rodents

Solution

Cry gene produce toxin protein that chocks the gut of insects in presence of alkaline pH to cause death of insects. It is not effective against rodents.
Question 6
1 / -0.25

The cry1Ac gene in Bt Brinjal is under the transcriptional control of an enhanced cauliflower mosaic virus 35S (CaMV35S) promoter, which ensures

A
control of the terminator

B
its concentration

C
the gene is expressed in all the Brinjal tissue throughout its complete life-cycle

D
its specificity

Solution

The cry1Ac gene in Bt Brinjal is under the transcriptional control of an enhanced cauliflower mosaic virus 35S (CaMV35S) promoter, which ensures the gene is expressed in all the Brinjal tissue throughout its complete life-cycle.
Question 7
1 / -0.25

Agrobacterium naturally inserts DNA into plants by

A
DNA

B
Its Ti plasmid

C
Marker gene

D
Antibiotic resistant genes

Solution

Using Agrobacterium vectors, nematodes-specific genes were introduced into the host plant. Agrobacterium naturally inserts DNA into plants by its Ti plasmid.
Question 8
1 / -0.25

Cry toxin is released from the crystal in the insect gut as

A
Due to the binding with the receptors

B
Due to sporulation

C
Alpha endotoxins are potent

D
Alkaline medium renders it soluble and amenable by proteases

Solution

Cry gene produce protein crystals in the insects gut as alkaline medium renders it insoluble and the activated toxin binds to surface of midgut epithelial cells and creates pores that cause cell swelling and death of the insect.
Question 9
1 / -0.25

Biotechnology has advantages over conventional breeding as

A
Growth rate is less

B
It is less time consuming

C
Growth rate is more but milk production is less

D
It is selective breeding

Solution

Conventional breeding programme takes several years to develops a new variety of crop. By use of biotechnology, required gene can be directly inserted into host plant to get required result.
Question 10
1 / -0.25

Which of the following methods should be used to increase crop production without use of chemicals and fertilizers?

A
Use of ancient technique of agriculture

B
Use of genetically modified crops

C
Use of organic fertilizers

D
Use of more water

Solution

Use of genetically modified crops may increase crop production many times without use of chemicals and fertilizers. Gene coding form higher nutrient and resistance to disease can be incorporated in crop.
