Genetic Engineering a Double Helix

In the 21st century you can see all the achievements in the medical field. Almost all of these advances are excellent but sometimes I think about the ethics behind it. No one says that it is wrong that other people help sick people, but they may say that the technology you are using is wrong. There is an ethical dilemma for placebo administration to patients undergoing research. They acknowledge registration for research and know that there is a possibility of taking placebo, but they want real treatment.

Since the development of genetics a century and a half ago, the discovery of the double helix structure of DNA 65 years ago, and since the mapping of the human genome 15 years ago, people told that science is studying Prometheus' flammable secret Noticed. . It is widely believed that genes determine the good or evil of our physiology, but the bigger controversy surrounds our psychology subject - our behavior and personality traits. One thing to say is to decide the speed at which genes predominantly run, the height of jumps, and vulnerability to myopia. But another way of thinking is that genes will also largely determine how clever we are, understanding, or antisocial. We tend to accidentally take into consideration the characteristics of the social construction brought about by the family and society environment where we are born.

In the past 50 years, the field of genetic engineering has developed rapidly for a deeper understanding of deoxyribonucleic acid (DNA) as a chemical double helix encoding gene production. The term genetic engineering is used to describe the process of changing the genetic composition of organisms using "recombinant DNA technology". This involves the use of laboratory tools to insert, modify or excise DNA fragments containing one or more genes of interest. Development of plant varieties showing excellent agronomic properties is the ultimate goal of plant breeders. However, with conventional plant breeding there is little or no guarantee that a specific combination of genes produced from millions of crosses will be obtained. Unwanted genes can be transferred along with the desired genes; or alternatively, when an ideal gene is obtained, both parent genes are mixed together and reassigned more or less randomly to the offspring Other genes are lost as they are classified.

After reading the double helix by James B. Watson, I learned that DNA double helix is ​​the source of the genetic code. It determines the characteristics to move from one generation to the next. The most surprising factor in determining the process of finding a DNA structure is how the X-rays are diffracted by helical molecules. Watson is tolerant of not knowing X - ray crystallography, but X - ray diffraction is one of the important elements to repeatedly argue and thus contributes to the discovery of DNA structure.
