1. Genetic engineering—Techniques to alter the makeup of genetic material (DNA and RNA), by introducing new genes into host organisms and thus change the phenotype of the host organism.
2. Maintenance of sterile (microbial contamination-free) environment in chemical engineering processes to enable growth of only the desired cell in large quantities for the manufacture of biotechnological products like antibiotics, vaccines, enzymes etc.
What is genetic engineering? Explain briefly the distinct steps common to all genetic engineering technology.
Or
With the help of diagrams show the different steps in the formation of recombinant DNA by action of restriction endonuclease.
