The key building blocks of life, known as nitriles, have been found in the heart of the Milky Way. International
Nitriles are important building blocksfor RNA—a DNA-like nucleic acid that is present in all living cells. According to new data, nitriles are among the most common chemical families in the Universe. This supports the origin of life hypothesis known as the RNA World.
Let us remember that this is a hypothetical stage of occurrencelife on Earth, when both the function of storing genetic information and catalyzing chemical reactions was performed by ensembles of ribonucleic acid molecules. Subsequently, from their associations, modern DNA-RNA-protein life arose, isolated by a membrane from the external environment.
New work by scientists confirms the hypothesis saysabout the fact that life on Earth was originally based only on RNA, and DNA and protein enzymes developed later. In addition, perhaps nitriles and other building blocks for life do not necessarily have to arise on the Earth itself.
The temperature of the molecular cloud at the center of ourThe galaxy is -173°C and its diameter is about 3 light years. At the same time, the mass of this m G + 0.693-0.027 is approximately 1,000 times greater than the mass of the Sun. So far, scientists have not seen signs of the formation of new stars in this cloud.
