John F. Enders develop the first vaccine for measles. The first vaccine for rubella is developed. Restriction enzymes are discovered. These enzymes cut DNA into pieces and are used for various studies and applications. The restriction enzyme technique becomes a fundamental tool in modern genetic research and opens the way for gene cloning. The DNA composition of humans is discovered to be 99 percent similar to that of chimpanzees and gorillas.

The purified enzyme reverse transcriptase is first used to synthesize complementary DNA from purified messenger RNA in a test tube. Stanley Cohen and Dr. Herbert Boyer use bacterial genes to perform the first successful recombinant DNA experiment, which inserted a recombinant DNA molecule into a cell for replication.

It becomes a seminal technology for studying the structure of DNA. The U. The first vaccine for chicken pox is developed in Japan.The term "biotechnology" dates fromwhen the Hungarian engineer Karl Ereky first used it to mean "any product produced from raw materials with the aid of living organisms.

Ancient civilizations even found that they could use microorganisms to make useful products, although, of course, they had no idea that it was microbes that were the active agents. About B. In about B. At the same time, the Chinese were adding bacteria to milk to produce yogurt.

For many, the term "biotechnology" is often equated with the manipulation of genes, but, as Ereky's definition suggests, this is only one aspect of biotechnology. For the more specific technique of gene manipulation, the term " genetic engineering " is more appropriate. Genetic engineering dates from the s. At that time molecular biologists devised methods to isolate, identify, and clone genes as well as to mutate, manipulate, and insert them into other species.

One of the key elements in such research was the discovery of restriction enzymes. These enzymes are able to cleave DNA at a limited number of sequence-specific sites and often leave "sticky ends.

By virtue of the "sticky ends," a hybrid molecule could be created that contained the gene of interest, which could then be inserted into such a cloning vector. The importance of restriction endonucleases was recognized in by the awarding of the Nobel Prize in physiology or medicine to Werner Arber, Daniel Nathans, and Hamilton Smith for their discovery of these enzymes.

The first experiment to combine different DNA molecules was performed in in the laboratory of Paul Berg who shared the Nobel Prize in chemistry for this work. Realizing the potential dangers of moving genes from one organism to another, approximately ninety prominent scientists, whose laboratories were poised to start cloning experiments, met in at the Asilomar Conference Center in California to discuss the potential dangers of gene manipulation. This meeting, wherein scientists recognized and openly discussed the ramifications and potential dangers of their research before that research was actually begun, was unprecedented.

The result of the Asilomar Conference was to call for and agree upon a one-year moratorium before any cloning experiments were to be done. This provided time to develop guidelines for the physical and biological isolation of recombinant organisms, to ensure that they not escape into the environment, and, if they did, to make sure that they would be so weakened as not to survive competition with naturally occurring organisms.

Bythen, gene cloning was in full swing around the world. Advances in biotechnology were marked by the development of key research techniques. InHerbert Boyer and Robert Swanson founded Genentech, the first biotechnology company to use recombinant DNA technology in developing commercially useful products such as drugs. The year is considered the "dawn of modern biotechnology," for it was in that year that the first human protein was cloned and manufactured using genetic engineering technology: Genentech reported the cloning of the human hormone somatostatin.

In Genentech was able to isolate the gene for human insulin and begin clinical trials that resulted in the approval and marketing of the first genetically engineered drug for human use. This was a major accomplishment.Looks like you are currently in Russia but have requested a page in the United States site.

Brian Colwell July 18, Humans have used biotechnology since the dawn of civilization.

After domestication of food crops corn, wheat and wild animals, man moved on to other new observations like cheese and curd. Cheese can be considered as one of the first direct products or by-product of biotechnology because it was prepared by adding rennet an enzyme found in the stomach of calves to sour milk.

Yeast is one of the oldest microbes that have been exploited by humans for their benefit. By 4,BCE, Egyptians used yeasts to bake leavened bread. Another ancient product of fermentation was wine, made in Assyria as early as 3,BCE. The Chinese developed fermentation techniques for brewing and cheese making. Hippocrates treated patients with vinegar in BCE. In BCE, Rome had over bakeries which were making leavened bread.

The use of molds to saccharify rice in the koji process dates back to at least A. One of the oldest examples of crossbreeding for the benefit of humans is mule. Mule is an offspring of a male donkey and a female horse.

Medical biotechnology: advancements and ethics.

People started using mules for transportation, carrying loads, and farming, when there were no tractors or trucks. By the 14th century AD, the distillation of alcoholic spirits was common in many parts of the world. Vinegar manufacture began in France at the end of the 14th century. In a book entitled BiotechnologieEreky further developed a theme that would be reiterated through the 20th century: biotechnology could provide solutions to societal crises, such as food and energy shortages.

Pfizer, which had made fortunes using fermenting processes to produce citric acid in the s, turned its attention to penicillin.Seems like this word has become a buzz word, nowadays. You will hear this word from classrooms to cafeterias. It can be commonly seen in newspapers, magazines, journals, and all sorts of media outlets, which include print media to electronic media.

People are organizing huge meetings, conferences, and workshops on biotechnology, where participants come from different arenas like science, industry, administration, social work, and so on. As time goes by and the way our life is heading it seems as if biotechnology has become an essential component of our life. The day is not far, when we cannot fathom our life without biotechnology. It is also possible that in future our birth and death can also be determined by biotechnology.

The probability and possibilities behind this kind of attention towards biotechnology may be due to its unlimited potential to serve and to benefit humanity. So far, biotechnology has touched our lives in all aspects, such as, food, health, and animal life. We have also noticed the importance and potential of biotechnology for the improvement of our environment and for better living, for example capability of biotechnology to meet the demand of depleting energy reserves of fossil fuels by replacing it with Bio-fuels, because availability of fossil-fuels are becoming limited to meet the demand of ever increasing population.

In simpler terms, our life starts with biotechnologically developed toothpaste, to drive car with biotechnologically developed fuels, and we also retire for the day with bedside medicines either to keep us healthy or to control chronic diseases, like diabetes, which makes our life better. If we try to decipher these two words, it simply suggests, in a lay-man's language, that it is the technology which makes our life convenient and comfortable with the employment of biological resources.

It is interesting to learn and understand how and when biotechnology really evolved. The term biotechnology was used for the first time by Karl Erkey, a Hungarian Engineer, in Was it the start of biotechnology?
