alleryGenetic engineering, in which genes are transferred between organisms to create new DNA, is also known as:
AHybridisation technique
BMutation breeding
CPolyploidy breeding
DRecombinant DNA technology
Answer & Solution
Correct answer: D. Recombinant DNA technology
1. Genetic engineering joins DNA from two sources to form recombinant DNA (rDNA).
2. Because DNA is recombined, the process is also called recombinant DNA technology.
3. Hybridisation, mutation breeding and polyploidy breeding are classical methods, not gene transfer between organisms.
4. Hence the answer is D.
