Regards appreciated community. Health.
Welcome to my blog.
Today I want to share with you one of the latest discovery that science has discovered that can be modified. It's about DNA.
As we know DNA. They are abbreviations that are used to summarize the term of this word that in its origin means deoxyribonucleic acid, a complex protein that is found in the nucleus of cells and is the main constituent of the genetic
The DNA. Its main function is the storage of all the information (functions and characteristics) necessary to synthesize, together with the RNA.
That is, the simple but polyvalent chain (ribonucleic acid), which plays several roles in vital proteins and in the development of an organism that is transferred from generation to generation. This information of the segments are known as genes.
It is important to note that genes are the storage units of genetic information, segments of DNA that contain all the information of the functioning of the cells of the organism.
Through the genes is that we can identify the similarity of the children with the parents and still know why they are different, in addition to recognizing the different species and varieties of animals and plants.
That said, he emphasized that scientists have taken giant steps now in the development of genetics and day by day they surprise the world, thanks to the latest technology available today. There are many findings that have shocked the world.
However I want to refer to the modification of DNA. Discovery that has been considered one of the most prominent in the genetic edition, since it has shown that humans could accurately intervene certain cells and correct errors in the DNA of people prone to develop hereditary diseases.
According to the investigations taken by El Heraldo. According to a recount of the scientific findings that marked a milestone in 2016, they prove that DNA can be modified satisfactorily, that is, to separate DNA, it would not be impossible.
How? Well this would be carried out from a small base of the genetic chain to a complete gene, which can be removed from its natural course to prevent malignant infections for humans.
WHAT IS A GENETIC CHAIN?
It is a composition composed of nucleotides which in turn is composed of a sugar (deoxyribose), a phosphate group and a nitrogenous base.
In addition, scientists and specialists have intervened in animal genetics and have managed to confirm that the DNA editing system works correctly.
Among the sample animals were mice, bucks and monkeys. In this regard Luis Montoliu (scientist and researcher) of the national center of Biotechnology explained the following:
"When living beings produce bacteria, they notify the RNA, which is responsible for carrying the message to the DNA and detect the affected gene to remove it."
He points out that this discovery is of utmost importance for people affected by HIV or muscular diseases that are detached from a specific gene, as well as avoiding an unfortunate offspring of negative DNA in future generations.
It is also important to highlight about this finding that the first known attempt to create genetically modified human embryos in the United States has been carried out successfully, according to the Technology Review, a specialized journal of the Massachusetts Institute of Technology.
According to the publication commented by the United States, to alter the genetic code of the DNA of human embryos, the objective of scientists is to show that they can correct or eradicate the genes that cause hereditary diseases.
It is also considered that this discovery will open new paths, new horizons that make it possible to safely and efficiently correct the defective genes that cause hereditary diseases.
It is worth noting that the fact of changing the human genetic heritage has now caused a stir of opinions in several countries of the world who are concerned about this finding. Situation that has caused that a great number of countries have signed an international convention that prohibits the genetic manipulation that seeks to modify the human lineage. About this Marcy Darnovsky director of the NGO center for genetics and society clarifies:
"The recommendations of this recent report are worrying and disappointing, as it represents a radically different position from the international agreement on the modification of human DNA"
Finally the scientific findings that marked a milestone in 2015 and 2016, prove that DNA can be modified and avoid negative evils in future generations.
