In today's world of high technology, biotechnology is particularly eye-catching. Scientists predict that in the 21st century, following electronics and information technology, biotechnology will lead to a new technological and industrial revolution that will once again change human society. The current revolution is quietly taking place in the medical field.
Biotechnology, including traditional fermentation engineering, cell engineering, and modern genetic engineering or recombinant DNA technology. Among them, genetic engineering is the most eye-catching.
On February 23, 1997, scientists used clone technology to breed the first cloned sheep. This news immediately caught the attention of the world and is still being heatedly debated.
In October 1997, there was another good news: scientists from the University of the Bath in Brescia developed a frog embryo without a head. This technique is used in humans to breed parts of humans, not the whole person. This kind of organ is used for human body transplantation, just like the original "accessory", there is no exclusivity. People who need organ transplants can use their own cells to "directively nurture" the organs they need.
"In order to not cultivate a complete embryo, you can use genetic techniques to change the developmental information of the embryo to suppress the development of certain organs and tissues of the human body," said Nathan Slack, a professor and embryologist at the University of the Bass. Except for the organs and tissues that are desired, as well as the heart and blood circulation system."
Scientists predict that in 2019, the replacement of this "self" accessory can be achieved - living organs and tissues cultivated through genetic engineering methods are widely used to replace patients' organs and tissues.
It should be noted that cloning technology has brought unlimited opportunities to mankind. In 1996, Nobel Prize winner and chemist Robert F. Cole once said: "The 20th century is the century of physics and chemistry, but the next 2l century will obviously be the century of biology." The birth of cloned sheep, biology The century suddenly came – many years earlier than expected, and came in the form of a sheep. Medicine, environmental protection, and agriculture will benefit the first batch, and the outlook is unpredictable.
Experts say that the cloning technology developed by the Roslin Institute in the United Kingdom provides an unprecedented opportunity to awaken all genes in mature cells, to reset the clock that controls cell development, and to unlock aging secrets.
Paul Rabino, an anthropologist at Stanford University who studies molecular biology and genetics, said: "The thousands of dollars (from biotech companies) have fundamentally changed the way Americans conduct scientific research."
In 1995 alone, medical researchers registered patents for 500 genetic engineering products. The rate of development of genetic engineering products is still accelerating. According to industry survey reports, researchers tested more than 284 new drugs in 1995, an increase of 20% over the previous year. These new drugs range from the common cold to the genetic engineering of AIDS. In fact, some of the 44 biotech drugs that have been approved for marketing have replaced other more conventional drugs.
Experts say: People are just beginning to feel the impact of new technologies. The wave of medical products, for the first time, comes from a fairly simple operation of life. The first batch of biotech products put on the market are almost all common human proteins secreted by genetically engineered bacteria. Researchers are perfecting more powerful genetic technologies for developing next-generation medical methods.
At present, biotechnology is more used in medicine. A better prospect is agriculture. There is a pioneer hybrid corn company in the United States. The seed production of corn is not in the farmland, but directly manipulates the corn DNA. It also produces new varieties that are resistant to disease, high yield, or have high oil content. In addition to saving money and farmland, it also greatly shortens the time. The person in charge of the company said: "Corn is no longer an agricultural product."
It is foreseeable that in the middle of the 21st century, the universal application of genetic engineering in agriculture will completely change the face of agriculture. For thousands of years, the era of peasants "facing the yellow earth back to the sky" will never return.
