The study, published in the journal Angewande Chemi, suggested that the trace element was D-ammonium Earth Before the advent of life, he called the tiny units of DNA «dioxy nucleosides»
After the chemical bonding process, things known in the scientific environment emerged with Neanderthal DNA, or early form of DNA on Earth
This discovery is one of many other similar discoveries in recent years., amid evidence that DNA and the chemically closest element «ARN» have evolved together into secretions For chemical reactions is similar
This scientific conclusion means that the two molecules which work to copy the first formula of life on Earth are a combination of the two, namely DNA and RNA
Researchers believe this important scientific discovery could lead to the emergence of new practical applications in chemistry and biology, but the most important is to paint a picture of the origin of life on Earth
On the other hand, this scientific discovery will lead to more specific studies to discover how the communication between DNA and RNA came about and how it spread on Earth in its primitive form, before it becomes a stage of biological maturation that appears in our present life, through bodies and materials
Ramanara Yana Krishnamurthy, chemistry researcher at Skyrips Center, said the latest discovery was an important step in the development of a detailed chemical model of the evolution of life on Earth.
This scientific conclusion shatters an idea that has been around for decades, with molecular duplication or reproduction processes initiated by RNA, while DNA appeared and was then made according to the organism using RNA
Ramanarayana researcher Yana Krishnamurthy and colleagues suspected it came from RNA, for the simple reason that its molecules were too sticky and did not allow this property to repeat or reproduce on its own
Scientists say RNA component can attract others «various components» individual DNA, which then attach to each other and integrate with each other.
