Transgenic plants are the ones:
Correct answer: A. Generated by introducing foreign DNA into a cell and regenerating a plant from that cell
- A. Generated by introducing foreign DNA into a cell and regenerating a plant from that cell
- B. Produced after protoplast fusion in artificial medium
- C. Grown in artificial medium after hybridization in the field
- D. Produced by a somatic embryo in artificial medium
Explanation
The plants produced through genetic engineering contain genes, usually from an unrelated organism. Such genes are called transgenes and the plants having transgenes are called transgenic plants. Recombinant DNA techniques are being used to improve crop plants by increasing their productivity, making them more nutritious, and by developing disease resistance. Transgenic plants have a natural resistance to herbicides and pests. In the future, plants may have an ability to fix atmospheric nitrogen and an increased ability to grow in arid and salty soils.

About Biotechnology
Biotechnology in health care applies biological organisms, cells or enzymes to diagnose and treat disease. The subject includes recombinant DNA, genetically engineered insulin, vaccines, antibiotics, monoclonal antibodies, gene therapy and techniques such as polymerase chain reaction, while distinguishing therapeutic applications from agricultural and industrial biotechnology.
