A. Bioprocess engineering: This technique is essential for large-scale production of biotechnological products, such as antibiotics, vaccines, enzymes, etc. It involves maintaining a sterile (microbial contamination-free) environment in chemical engineering processes to allow the growth of only the desired microbe or eukaryotic cell in large quantities for manufacturing biotechnological products.

B. Somatic hybridisation: Isolated protoplasts from two different varieties of plants – each having a desirable character – can be fused to get hybrid protoplasts, which can be further grown to form a new plant. These hybrids are called somatic hybrids while the process is called somatic hybridisation. When a protoplast of tomato is fused with that of potato, and then they are grown – to form new hybrid plants combining tomato and potato characteristics – resulting in formation of pomato.

C. Gene therapy is a collection of methods that allows correction of a gene defect that has been diagnosed in a child/embryo. Here genes are inserted into a person’s cells and tissues to treat a disease. Correction of a genetic defect involves delivery of a normal gene into the individual or embryo to take over the function of and compensate for the non-functional gene. The first clinical gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency.

D. Biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment.
