The genetically-modified (GM) brinjal in India has been developed for

1. insect-resistant

2. enhancing self life

3. enhancing mineral content

4. drought-resistance

Genetic engineering has been successfully used for producing

(1) transgenic mice for testing safety of polio vaccine before use in humans

(2) transgenic models for studying new treatments for certain cardiac diseases

(3) Transgenic cow-Rosie which produces high fat milk for making ghee

(4) animals like bulls for farm work as they have super power

Some of the characteristics of Bt cotton are

(1) long fibre and resistance to aphids

(2) medium yields, long fibres and resistance to beetle pests

(3) high yield and production of toxic protein crystals which kill dipteran pests

(4) high yield and resistance to bollworms

An improved variety of transgenic basmati rice

(1) does not require chemical fertilizers and growth hormones

(2) gives high yield and is rich in vitamin-A

(3) is completely resistant to all insect pests and diseases of paddy

(4) gives high yield but has no characteristic aroma

The bacterium Bacillus thuringiensis is widely used in contemporary biology as a/an

(1) indicator of water pollution

(2) insecticide

(3) agent for production of dairy products

(4) source of industrial enzyme

The genetic defect-Adenosine Deaminase (ADA) deficiency may be cured permanently by

(1) periodic infusion of genetically engineered lymphocytes having functional ADA cDNA 

(2) administering adenosine deaminase activators

(3) introducing bone marrow genes producing ADA into cells at early embryonic stages

(4) enzyme replacement therapy

Which of the following is not used as a biopesticide?

(1) Bacillus thuringiensis

(2) Trichoderma harzianum

(3) Nuclear Polyhedrosis Virus (NPV)

(4) Xanthomonas campestris

What is true about Bt toxin?

1. The inactive protoxin gets converted into active form in the insect gut

2. Bt protein exists as active toxin in the Bacillus

3. The activated toxin enters the ovaries of the pest to sterilize it and thus prevent its

multiplication

4. The concerned Bacillus has antitoxins

A transgenic food crop, which may help in solving the problem of night blindness in developing countries is:

1. Flavr savr tomatoes

2. Starlink maize

3. Bt soybean

4. Golden rice

Cry-I endotoxins obtained from Bacillus thuringiensis are effective against

(1) mosquitoes                         
(2) Nematodes
(3) boll worms                         
(4) Flies
