Question

What are transgenic bacteria? Illustrate using any one example.

Answer 1

Transgenic bacteria are the genetically modified bacteria that carry the gene from other sources and are used for the production of desired gene product at large scale. For example, isolation of human insulin gene from the human genome and formation of rDNA carrying the insulin gene is followed by the introduction of rDNA (vector DNA + insulin gene) into E. coli. The bacterial cells carrying the rDNA called as transgenic bacteria and serve to produce insulin protein at large scale.
