Biology is the science of living organisms. It is not surprising that at the beginning of the XXI century it came to the forefront among other sciences, because achievements in the field of medicine, selection, genetics are associated with the discoveries of biologists.
The practical significance of biology
Most of us did not think about how the contribution of science can affect the future. Already today, scientists have revealed the human genome, they can derive new varieties of plants and animal breeds. Work is underway on the synthesis of antitumor substances. The medicine of the future will be entirely based on biology.
What is the practical significance of general biology? It is important to understand how any cell in the body functions and what processes take place there. You can also find out how cells divide and what the human genome is. The development of general biology can give an idea of how our body functions.
The practical significance of biology in life is enormous, because more than once you probably were helped by the knowledge gained back in school, when you took out your first-aid kit or tried to derive any laws of nature for yourself. Now the world faces a global environmental problem. Here, the practical significance of biology cannot be overestimated, because knowledge of the features of the development of organisms in nature can greatly help in preserving the environment, including flora and fauna.
Breeding and genetic engineering
The problem of hunger affects a huge number of countries. In order to increase the volume of the obtained crop from crops, it was necessary to carry out work to improve the plant genome. Scientists have achieved success in the field of breeding, and now the number of products obtained from crops has increased 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 large mass. This is also the practical significance of biology.
Genetic engineering and selection are inseparable. Thanks to these two branches of biology, similar results were achieved. Breeding new varieties, breeds and strains is directly related to genetics, because the laboratory is working with the genomes of organisms at the DNA level. The genes that are necessary for humans are integrated into the genomes of plants, animals and bacteria. As a result, organisms gain resistance to some unfavorable factor, increase their yield, etc.
Molecular biology and medicine
What will the medicine of the future be based on? The determination of the nucleotide sequence of the human genome is no longer a myth. A large number of diseases are associated with mutations in genes. Due to any abnormalities in the DNA molecule, people are allergic 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 necessary for humans. Product technology is based on the use of bacteria. How does this happen?
Man has learned to incorporate the genes he needs into the genetic information of bacteria. Since prokaryotes divide very quickly, they thereby increase copies of these genes. Such producer bacteria are used, for example, in the production of insulin, which means it is very effective.
Evolution
The problem of evolution excites man today. Where did we come from? How did the evolution of organisms on Earth actually take place? To answer these questions, new discoveries in the field of biology are needed.
The practical significance of biology is so great that even today, scientists were able to clarify some of the details of evolution. However, they have not yet answered the main questions of the origin of man. Revealing all the secrets of evolution is one of the main goals of modern biology.
