Well, the microscope is a wide world, there are even many kind of micro or nano worlds, for example: the world of bacteria, the molecules, the atoms, etc... But the micro or nano world that I like more is world of molecules because is the base of the all cell processes, very important for understand the life, is one of the reasons why I choose biochemistry.
The one that I consider the most incredible and mysterious molecule of all is the DNA, this molecule has the code of life. The interesting thing is that we can modify it, creating new characteristics in an individual, is a branch of science called "genetic engineering" is based on transferring genes from one species to another, improving or generating some missing characteristic.
Genetic modification is important for biochemistry because is the most studied subject, since DNA is the most important molecular of life.Genetic modification example: modify vegetables to better withstand drought, to make bacteria produce insulin by entering the gene that can produce insulin or transferred DNA from tardigrade to human cells, to increase its resistance to radiation.
But not everything is good, the genetic modification is a powerful tool that if not one carefully can be used for evil, either using it to create deadly bacteria, or modifying species giving it a more advantageous feature than other species causing the extinction of these.
Genetic engineering remains a developing science that can responsibly improve the quality of life of people.
interesting technique
