What are transgenic bacteria? Illustrate using any one example.
Those bacteria whose DNA is manipulated to possess and express an extra (foreign) gene are known as transgenic bacteria. Example: Human Growth hormone production by transgenic Escherichia coli. The pituitary gland of humans produces growth hormones that regulate growth and development. However, in children stunted growth occurs due to deficiency of the hormone which is called pituitary dwarfism. For this, the hGH is now available as a recombinant protein.
