Science and technology play a huge role in our society as well as in our lives. Nowadays we all are surrounded by technology and are dependent on it for everything we do. Especially after this pandemic everything is in virtual mode and is completely based on technology. We live in the technological era where gadgets are of outmost importance to us. A gadget is simply a human made device which is programmed to reduce human effort and does a piece of job easily without any hassle.
In this fast-growing world we human beings are always surrounded by machines and gadgets for every need of ours starting from the time we get up in the morning till we again go to bed we even use gadgets while we are asleep such as air conditioner, insect repellent and many more. Science is a boon for us, but in the other hand as everything has its own merits and demerits there are also people who do use science for a bad cause. Technology is good but it is advisable to keep this technology out of the reach of children as otherwise they will not tend to learn things and will prefer to take the help of science to solve a particular existing problem this may affect their growth.
IMPORTANCE OF SCIENCE AND TECHNOLOGY :
Technology, science and knowledge are important in modern contemporary society. Essential questions include the following : How does science and technology produce new products, new ways of living and new nutritious? Why is new technology and knowledge so fundamental to us in the ways through which we imagine the future?
Technology, knowledge and science are fundamental in modern contemporary society. The understanding of how social, cultural and material elements influence the production of new practices, new ways of under of contemporary postmodern society. Studies of technology and science provides students with insight into how different processes of knowledge are initiated and progressed, and how innovative technological processes are developed employed and increase in importance.
In this manner, students will be provided with the academic basis for working with detailed analyses of different forms of technologies and process of knowledge within business life or industry and commerce, research work , political development, management of knowledge and innovation.
THE RELATIONSHIP BETWEEN SCIENCE AND TECHNOLOGY :
Science , technology and innovation each represent a successively larger category of activities which are highly interdependent but distinct. Science contributes to technology in at least six ways.
THe ROLE OF SCIENCE AND TECHNOLOGY
Teaching technological literacy, critical thinking and problem- solving through science education gives students the skills and knowledge they need to succeed in school and beyond.
SCIENCE AND TECHNOLOGY USED IN SOCIETY :
Science and technology have had a major impact on society, and their impact is growing. By making life easier, science has given an the chance to pursue societal concerns such as ethics, aesthetics, education and justice to create cultures, and to improve human conditions.

Biotechnology branch of biology deals with the the techniques of using living organism or enzymes to produce useful product for human welfare.
European federation of biotechnology (EFB) has has given a defination of biotechnology from both traditional and modern molecular biotechnology point of view. The definition given by EFB is as follows :
“The integration of natural science and organisms,cells,parts thereof, and molecular analogues for products and services”
Engineer Karl Ereky first coined the term ‘biotechnology‘ in 1919, meaning the production of products from raw materials with the aid of living organisms
Humans have used biotechnology since the dawn of civilization. Egyptians used yeasts to bake leavened bread, the Chinese developed fermentation techniques for brewing and cheese making, and the Aztecs used Spirulina algae to make cakes. Today, when most people think of biotechnology, they probably think of recombinant DNA. Although much of modern biotechnology does deal with manipulating DNA, classical biotechnology began long before we even knew about genes or chromosomes. What began as recipes for production of food now includes technology to enhance everything from farming to pharmaceuticals.
principles of biotechnology.
Traditional biotechnology
Traditional biotechnology refers to ancient ways of using living organisms to make new products or modify existing ones. An example of traditional biotechnology is what human beings have been doing for centuries: cloning plants. Each time a little branch is cut off from a plant and placed in soil to grow a new plant, cloning occurs. Over the past 30 years, biologists have increasingly applied the methods of physics, chemistry and mathematics in order to gain precise knowledge.
Modern biotechnology
Modern biotechnology we are not only doing the physical manipulation at the visual level but also at the molecular level. In modern molecular biotechnology, we select the desired characteristic at the molecular level and add it to the organism’s genetic makeup. Whereas traditional biotechnology exploits the potential of processes performed by living organisms, such as fermentation, modern biotechnology manipulates the genes of organisms and inserts them into other organisms to acquire the desired trait.
However, both traditional and modern biotechnology share the same foundation: the use of living organisms to enhance crops, fuels, medical treatments and other tools to help humans.
Among many, the two core techniques that enabled birth of modern biotechnology are:
1. Genetic engineering : Techniques to alter the chemistry of genetic material (DNA and RNA),to introduce these into host organisms and thus change the phenotype (physical character) of the host organisms.
2.Chemical engineering : Maintance of sterile microbial contamination free ambience in chemical engineering processes to enable growth of only the desired microbe/ eukaryotic cell in large quantities for the manufacturing of biotechnological products like antibiotics, vaccines, enzymes, etc.
Stanley Cohen and Herbert Boyer in 1972 isolated the first recombinant DNA and the antibiotic resistance gene by cutting out a piece of DNA from a plasmid( autonomously replicating circular extra- chromosomal DNA) which was responsible for conferring antibiotic resistance.
The cutting of DNA at specific locations became possible with the discovery of the so- called ‘molecular scissors’ – Restriction enzymes
Biotechnology is the emerging field nowadays and in coming future it will be the important part For the development of the country. By manipulating genes we can produce more and more useful products for the human welfare.
