Biology is the science of living organisms.It is not surprising that at the beginning of the 21st century it reached the first line among other sciences, because achievements in the field of medicine, breeding, genetics are related to the discoveries of biology scientists.
The practical importance of biology
Most of us did not think howThe contribution of science can affect the future. Even today, scientists have uncovered the human genome, can derive new varieties of plants and animal breeds. There is work on the synthesis of antitumour substances. The medicine of the future will be completely based on biology.
What is the practical significance of the generalbiology? It is important to understand how any cell in the body functions and what processes are taking place there. And you can also learn how cells are divided and what the human genome is. The development of general biology can give an idea of how our body functions.
The practical importance of biology in life is enormous,because more than once you probably helped the knowledge obtained in school, when you got a first aid kit or tried to deduce for yourself any patterns of nature. Now the global environmental problem is facing the world. Here, the practical importance of biology can not be overemphasized, since knowledge of the features of the development of organisms in nature can greatly help in preserving the environment, including flora and fauna.
Selection and genetic engineering
The problem of hunger affects a huge numbercountries. To increase the volume of crops from crops, it was necessary to work on improving the genome of plants. Scientists have achieved success in the field of breeding, and now the number of products obtained from crops has grown several times. The same applies to breeding new breeds of animals. Now a person can breed animals that bring more wool, give more milk, have a greater mass. This is also the practical significance of biology.
Genetic engineering and breeding are inseparable from each otherfriend. Thanks to these two branches of biology, similar results were achieved. The breeding of new varieties, breeds and strains is directly related to genetics, since in the laboratory works with the genomes of organisms at the DNA level. Genes that are necessary for humans are built into the genomes of plants, animals and bacteria. As a result, organisms get resistance to some unfavorable factor, increase their yield, and so on.
Molecular biology and medicine
What will the future medicine be based on?Determining the nucleotide sequence of the human genome is no longer a myth. A large number of diseases are associated with mutations in the genes. Due to any abnormalities in the DNA molecule, people suffer from allergies or may experience side effects of the drugs during treatment. All this in the near future can be detected by sequencing the genome of each individual person and making individual genetic passports.
Today, there are entire enterprises for the production of drugs or substances needed by man. The technology of the products is based on the use of bacteria. How does this happen?
The man has learned to build the genes he needsin the genetic information of bacteria. Since prokaryotes are divided very quickly, they thereby increase copies of these genes. Such producer bacteria are used, for example, in the production of insulin, which means that it is very effective.
Evolution
The problem of evolution worries man even today.Where did we come from? How did the evolution of organisms on Earth actually occur? To answer these questions, new discoveries in the field of biology are needed.
The practical importance of biology is so great,that even today scientists have been able to clarify some details of evolution. However, they have not yet answered the main questions of human origin. To reveal all the mysteries of evolution is one of the main goals of modern biology.
