1.	What are transgenic bacteria? Illustrate using any one example.
Answer» Transgenic bacteria are microbes carrying clones of foreign genes. It is also known as genetically modified bacteria. These bacteria are being employed for many functions . (a) Two DNA sequence (coding for A and B chains of human insulin) were introduced into the plasmid of bacteria E. Coli. This transgenic bacteria produced insulin chain- Used as biochemical factories (b) Microbes have been genetically changed to help in cleaning the polluted environment, eg:- Pseudomonas putida for cleaning oil spills pseudomonas species for removing heavy metal pollutants. Aceto bacter aerogans for decomposition of DDT and Flavobacterium for decomposition of 2,4-D.
