If DNA from two different sources is fused
Correct answer: A. Recombinant DNA is formed
- A. Recombinant DNA is formed
- B. Complementary DNA is formed
- C. Mutant DNA is formed
- D. cDNA is formed
Explanation
Recombinant DNA (rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) to bring together genetic material from multiple sources, creating sequence that would not otherwise be found in the genome. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure. However, a recombinant DNA formed by the fusion of DNAs taken from two organisms have remotest evolutionary relation is called chimeric DNA as well.

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.
