What is the human genome

At that time, when you read these words, or drink their morning coffee, watching TV or fast asleep, covered with a blanket, powerful computers methodically and organize research materials, which in the first place among the research is the human genome.

Computers under the guidance of scientists geneticists carefully cataloging the tens of thousands of genes contained in human DNA.According to the predictions of scientists that will be collected and entered into the computer all the necessary information, it will long serve as a basis for the study of human biology and for medical purposes.

Scientists also hope that after the human genome is completely deciphered, will open the way for humanity to therapy, people learn to adjust or replace defective genes.

Doctors also hope that after the human genome to be fully investigated as science learns easily "read" it, you should see a new generation of medicines that will be safer, but it is very effective in combating the disease and preventing them.

Perhaps, this technology will also allow the doctor to review your genetic data, to determine in advance which drugs are best for you.

Besides the prospects opening up before the doctor, someone suggests that human genetic engineering is able to solve many social problems.During the period since the Second World War and ending with the beginning of the 1990s, scientists have proved that it is possible to reduce social problems, to reform the economy and the various institutions and improve people's living conditions.However, in recent years, only increased social problems.Therefore, many psychologists, sociologists and journalists hypothesized that the solution to these problems must be sought in the genes.Today, some think that the genes more than the environment, affect the behavior of the individual and the whole group.

Also, according to the researchers, even this problem can be solved by spending some DNA manipulations.Scientists have managed to double the length of the existence of fruit flies and worms, and they honestly believe that the same technique could be someday be applied to people.Head of the project "Human Genome" said: "The first time we can think about the reality of human immortality."

«Ha - ha!- Laugh at the last statement of the cynics.- Compare, too: some fruit flies and worms - and such a highly developed system, like a man! "Well, let the cynics laugh, how much they will get.However, it may seem strange to anyone looking for an answer to the question of how many genes in humans, scientists have concluded that their number is not much greater than the number of genes in a simple organism such as a large worm.More specifically about this, about what a person has 28,000 genes (it is instead alleged 100,000, as expected, scientists, starting to project).

Although today medicine is widely used in the science of genetics for their own purposes.For example, there is the most common method of genetic testing human embryo, which is already applied to the 1960s.

To analyze the doctor inserts the needle of the syringe into the uterus of a pregnant woman through the belly button and takes a sample of amniotic fluid.Then, this liquid was examined in order to identify, whether the fetus does not have any serious genetic disorders.

This is absolutely harmless for the future mom, and for her offspring procedure is able to warn of such violations in the development of the fetus, as the development of Down syndrome or spina bifida.

However, not all detected abnormalities in the developing fetus, modern medicine can eliminate.In most cases, it can simply make a tragic verdict: "It needs an abortion!»

so precisely in order to learn not just to kill an unborn patient man, and adjust its development at an early stage, to eliminate unwanted changes to the fetus through genetic engineering, andscientists are trying to solve the mystery of the human genome.
