A) Bt in Bt-cotton indicates that it is a genetically modified organism produced through biotechnology
B) Somatic hybridization involves fusion of two complete plant cells carrying desired genes
C) The anticoagulant hirudin is being produced from transgenic Brassica napus seeds
D) Flavr Savr variety of tomato has enhanced the production of ethylene which improves its taste
Correct Answer: C
Solution :
Bt in Bt cotton stands for Bacillus thuringiensis, a soil bacterium from which bt gene (encoding Bt toxin) is obtained. Somatic hybridisation involves the fusion of protoplast (i.e., cell minus cell wall) of two cells. Flavr-savr is a transgenic tomato with hard skin and improved flavour and recombinant hirudin is an anticoagulant which is being produced in transgenic Brassica napas at commercial scale.
