Golden rice is a genetically modified crop plant where the incorporated gene is meant for
biosynthesis of
1. vitamin-B
2. omega 3
3. vitamin-C
4. vitamin-A
In Bt cotton, the Bt toxin present in plant tissue as pro-toxin is converted into active toxin due to
(1) Alkaline pH of the insect gut
(2) acidic pH of the insect gut
(3) action of gut microorganisms
(4) presence of conversion factors in insect gut
A single strand of nucleic acid tagged with a radioactive molecule is called
1. vector
2. selectable marker
3. plasmid
4. probe
The process of RNA interference has been used in the development of plants resistant to
(1) fungi
(2) viruses
(3) insects
(4) nematodes
Maximum number of existing transgenic animals is of
(1) mice
(2) cow
(3) pig
(4) fish
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
DNA or RNA segment tagged with a radioactive molecule is called
1. vector
2. probe
3. clone
4. plasmid
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
