BIOTECHNOLOGY AS AN OPTIONAL SUBJECT



IIn the words of an ex student (KULDEEP SHARMA)

I knew that I would opt for science in class 11. The problem, however, was to choose the fourth and fifth subjects. I was sure that I would not take biology since I love mathematics. I choose biotechnology as the fifth subject, oblivious to what it entails.
Biotechnology is a highly interdisciplinary subject. It includes biochemical engineering, life science, genetic engineering, material science, and bioinformatics: it goes beyond biology. Learning these basic concepts in class 11 and 12 provides a template to continue for higher studies in the same field. I enjoyed learning the subject, and never imagined that I would spend my next seven years in the same area.  
The 21st century belongs to biology since the field is relatively unexplored. Recent Nobel Prizes have been conferred to work mostly related to biology. Biotechnology is the most expensive laboratory in any academic institution. Researchers from disparate backgrounds are now incorporating some aspect of biology in their research work. In India, the Department of Biotechnology is a separate department under the Ministry of Science & Technology. 
Recent advancements in the field have led to several breakthroughs. A newly developed system - CRISPR-Cas9 - is a gene-editing tool that allows DNA to be added, removed, or modified at particular locations. DNA based data storage devices are a new reality. In June 2019, scientists encoded all 16 GB text from Wikipedia’s English-language version into the synthetic DNA. The unprecedented COVID-19 pandemic has led everyone to realize the importance of this field. Detection kits, vaccines, and antibodies find their place in contemporary public discourse. 
The biotechnology sector is growing at a rate of 12% over the last five years, with a turnover of ₹28,185 crores in 2014-15. By the end of 2025, it will touch the $100 billion mark in India. The career prospects are bright, but it requires immense effort. You can become whatever you love to: researcher, data scientist, academician, pedagogue, intellectual property agent, science journalist, scientific advisor, forensics expert, and entrepreneur. 
About the author:
Kuldeep is pursuing M.Tech. in Biological Engineering at IIT Gandhinagar. He is yet to submit the Master’s Thesis. 

NOW WE SHOULD KNOW ABOUT BIOTECHNOLOGY:

Biotechnology is the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.

Or simply we can say,  In biotechnology, living organisms are used to make useful chemicals and products or to perform an industrial task.

Biotechnology is the field of science that involves the use of living things in various fields as engineering, technology, medicine etc.

People still think that biotechnology is only about biology. But that is not it seems to be. Knowledge of mathematics adds up to be an important to make your career in this field.

Thus, I can say biotechnology as 5th subject with SCIENCE even with MATHEMATICS is a good combination or we can say is a need of hour.

AFTER 12TH: 
  • B.TECH(BIOTECHNOLOGY)
  • B.TECH (FOOD TECHNOLOGY)
  • B. TECH (DAIRY TECHNOLOGY)
  • B.TECH (BIOMEDICAL ENGINEERING)
  • B.TECH (AGRICULTURAL ENGINEERING)
  • B.TECH (ENVIRONMENTAL ENGINEERING)
  • B.TECH (BIOINFORMATICS)
  • B.SC.(BIOTECHNOLOGY)
  • B.SC. (BIOCHEMISTRY)
  • B.SC. (MICROBIOLOGY)
ELIGIBLE TO APPEAR IN NEET: NATIONAL ELIGIBILITY CUM ENTRANCE TEST for admission to MBBS/BDS Courses

These are among lesser known fields of engineering which are in great demand in present scenario. These courses are offered by few government institutes and due to less awareness the students are not able to take the full benefit.

And, thus the list goes on ..........................

Application of biotechnology

A DETAILED LIST IS ATTACHED BELOW

Now, we should discuss about the CAREER IN BIOTECHNOLOGY:
A number of factors determine the demand of professionals from this interdisciplinary field.The applications of this branch of science are vast and simply mind-boggling. On one hand, it caters to the industrial sector such as food and beverages industry, textiles industry, biological products, medicines and pharmaceuticals while on the other hand this branch of science caters to the requirements of agriculture, animal husbandry, nutrition and environmental conservation. The list is a long and an envious one.

Although, the name may suggest that this branch of science is steeped in biology but this is not the case. Apart from biology, this branch of science also assimilates diverse subjects like physics, chemistry and mathematics. Furthermore, engineering applications are also an integral constituent of biotechnology.

Step-by-Step
In opting for a specialised profession such as biotechnology, you must plan your career right from your school days. In this context, the combination of subjects of study at the 10+2 level must primarily include Biology, Chemistry, Physics and even Mathematics. Among all you are at edge that you can opt this subject at class 11. Once you have finished schooling you can opt for a suitable undergraduate program (BSc, BE, BTech) in Biotechnology from various academic institutions spread across the country. The duration of a BSc program in biotechnology is three years whereas it is four years for BE and BTech courses.

IN THE NEAR FUTURE YOU WOULD BE:
Agricultural and Food Scientist
The Bureau of Labor Statistics (BLS) combines three related careers under the heading of agricultural and food scientist: animal scientist, food scientist and technologist, and soil and plant scientist. Although all have the ultimate task of improving farm productivity, they accomplish this in different ways.

Agricultural Engineer
Many people don’t think of farming as being sophisticated. Seeds are planted, crops are watered, and eventually food is harvested. But it is an extraordinarily advanced field, and the largest farms are essentially food factories. Engineers are involved in research and development as well as manufacturing. They might oversee water supply and usage, design comfortable areas for the animals, and create machines that can efficiently harvest crops with minimal food loss. Agricultural engineers spend their time both in offices designing systems and on farms testing and applying those systems.

Animal Scientist
Farm animals can be crossbred to produce better quality meat, eggs or milk. They can also be bred to live longer, healthier lives, saving farmers money. Animal scientists have the expertise in genetics and reproduction to crossbreed effectively so that farmers can increase production and lower costs.


Biochemist and Biophysicist
These scientists spend most of their days in large laboratories researching how living things function. They plan experiments; work directly with protein, enzymes and DNA; and study the effect of external substances on living things. Those who work for biotechnology companies or divisions work in applied research, meaning they are looking to use their findings to solve a specific problem. For instance, in the past, biochemists in agriculture have used applied research to genetically modify rice to have more beta-carotene and, by extension, vitamin A. This rice could be used in parts of the world where rice was a staple food but vitamin A deficiency was a major killer. Biophysicists working for energy companies, meanwhile, have made advances in developing fuel such as ethanol from plants.

Biomedical Engineer
These product-makers either create tools to analyze medical problems or design tools that improve patients’ lives. For instance, they can create better microscopes or newer imaging technologies. More pertinent to the field of biotechnology, however, is their work to create artificial limbs that respond to brain signals or the recent invention of a bionic pancreas that eliminates the need for insulin injections in people with diabetes.

Microbiologist
Microbiologists research bacteria, viruses, fungi, algae and parasites — basically anything too small to be seen with the naked eye. The field is highly specialized, meaning that most microbiologists focus on studying just one type of microorganism. In the context of biotechnology, microbiologists might work in the manufacturing side of the industry, making sure that products are not contaminated, but they are just as likely to be involved in research and development. The Bureau of Labor Statistics Occupational Outlook Handbook provides the following example: “They may study the use of microbes to clean up areas contaminated by heavy metals or study how microbes could aid crop growth.”

REPUTED DEPARTMENTS OF INDIA THAT ACCOMMODATE BIOTECHNOLOGISTS :

  • BUREAU OF POLICE (R&D)
  • DRDO
  • MINISTRY OF AYUSH RESEARCH FELLOWSHIP
  • BARC PRACTICAL TRAINING PROJECT WORK
  • NATIONAL CENTRE FOR CELL SCIENCES
Biotechnology is an emerging field and the day is not so far that the world will be conquered by it, leaving behind the field of IT. So don’t confine yourself with the feeling of Biotechnology having no scopes. Biotechnology is beyond biology and is having a good scope in the field of R&D, Quality Control, and Administration. The field is growing at a good pace and still, there is a long way to go.
