Question

Genetic engineering is possible because:

• A. the phenomenon of transduction in bacteria is well understood
• B. restriction endonuclease purified from bacteria can be used in vitro
• C. we can see DNA at specific setes by endonucleases like DNAase I
• D. we can see DNA by electron microscope

Answer 1

Answer: (B)

Genetic engineering also known as ?Recombinant DNA technology?, ?Genetic manipulation? and ?Gene cloning?. The pioneer of genetic engineering is Dr. Har Govind Khorana. In this technique restriction endonucleases enzymes are used which cut the larger DNA into shorter fragments at specific nucleotide sequence. The research is centred on in vitro joining of DNA fragments of different origin.
