Which one of the following is a correct statement?

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
✓
The anticoagulant hirudin is being produced from transgenic Brassica napus seeds
D
Flavi savr variety of tomato has enhanced the production of ethylene, which improves its taste

✓

Answer

Correct option: C.

The anticoagulant hirudin is being produced from transgenic Brassica napus seeds

c
$Bt ^{\prime}$ in $^{\prime} Bt ^{\prime}$ cotton stands for Bacillus thuringiensis, a soil bacterium from which Bt gene (encoding Bt toxin) is obtained. Somatic hybridization 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 flavor and recombinant hirudin is obtained from the seeds of transgenic Brassica napas at commercial scale.
