There are plenty of explanations of what biotechnology is, but the simplest one is that it is a field of study where biology is the foundation on which different kinds of technology are developed. Biotechnology is the basis of many different kinds of research in the fields of environment, food science, robotics, agriculture and medicine.

People have always tried to manipulate the environment, but never before have we been so close to controlling it. It started from the time when we started fermenting beer, which went to another level when bacteria were cultured. Now we have moved forward to a point where animal cloning and advanced forms of nucleotide-based organ regeneration are being attempted successfully.

But even before there was a name to call it by, biotechnology was in existence. Even something that people have been doing for centuries, like preservatives to keep food edible during winter, is a form of biotechnology. When around 6000 BC, fruit juice was first fermented to form alcohol, it was another instance of biotechnology. Of course, it has emerged as a science only recently.

DNA and genetics played a big part in bringing biotechnology as a science to the forefront. It was recognized as a science when it was discovered that genetics were what played the major part in the synthesizing of essential proteins in any organism.

The mid 80s brought a revelation in biotechnology - genetic structures could be modified by careful combinations between animals and plants. This introduction to transgenic organisms also developed an area for further research into disease resistance and productivity rate increases. Modern biotechnology is used in a variety of ways and the medical and biological research fields have managed to get the most benefit out of it. The methods used have gone beyond ordinary genetic transfers, to include actual plant-generated pharmaceuticals and substance production for antibiotics and insulin.

There are three categories in modern biotechnology. The first is red biotechnology. This concerns the making of substances used in medicine and pharmaceuticals, like vaccines, proteins, antibiotics and vitamins. Red biotechnology also deals with genome manipulation. The other two kinds of biotechnology are green and white biotechnology.

White Biotechnology is also called bio-manufacturing, or Grey Biotechnology. In this field, live organisms are changed and controlled to produce industrial chemicals. The organisms that White Biotechnology uses are moulds, enzymes, yeast and bacteria.

Green Biotechnology is important in agriculture - making better produce that stays fresh and lasts longer, and is more nutritious. This is something people have been doing for a long time - making sturdier crops, like cross-bred wheat for example.
