Q & A

What is biotechnology and how has it been utilized in the past?

Biotechnology involves utilizing living organisms or their products to improve human health, the environment, or industrial processes. Historically, it has been used for thousands of years, such as in beer brewing, winemaking, and food preservation, even before the term 'biotechnology' was coined.

What are the major areas of biotechnology applications?

The nine major areas of biotechnology applications are: bio-processing technology, monoclonal antibodies, cell culture, recombinant DNA technology, cloning, protein engineering, biosensors, nanobiotechnology, and microarrays.

What is bio-processing technology, and how has it been used historically?

Bio-processing technology involves using living cells to produce valuable products. Historically, it has been utilized in processes like beer brewing, winemaking, bread making, and pickling, without the scientific understanding we have today.

How are monoclonal antibodies used in biotechnology?

Monoclonal antibodies are used to detect pollutants, identify harmful microorganisms in food, differentiate between normal and cancer cells, and diagnose infectious diseases in humans, animals, and plants.

What does cell culture involve, and what types exist?

Cell culture involves growing cells outside of a living organism. The three types are plant cell culture, insect cell culture, and mammalian cell culture.

What is recombinant DNA technology and what are its uses?

Recombinant DNA technology involves recombining DNA from different species to create new medicines and vaccines, slow food spoilage, control viral diseases, and reduce inflammation, among other applications.

What is cloning technology, and what is its significance?

Cloning technology allows for the generation of genetically identical organisms, cells, or molecules. It gained attention with the cloning of Dolly the sheep and has various applications in research and biotechnology.

What role does protein engineering play in biotechnology?

Protein engineering is a recombinant DNA technique used to improve existing proteins or create new ones that do not exist in nature. These engineered proteins can be used in food processing, drug development, and industrial manufacturing.

How do biosensors work and where are they used?

Biosensors combine biology with microelectronics to detect and measure substances at extremely low concentrations. They are used in food safety, detecting explosives, measuring pollutants, and providing critical medical measurements in emergency rooms.

What is nanobiotechnology, and what are its potential benefits?

Nanobiotechnology involves the study and manipulation of ultra-small structures and machines, which can improve drug delivery, speed up disease diagnosis, and promote green manufacturing practices.
