In an article published in the Journal of Scientific Reports, Professor Tomonori Totani of the University of Tokyo observed how the basic components of life can form spontaneously in a process known as abiogenesis.
And how that information was revealed by abiotic processes is an important issue. We can be the only intelligent life in the observable universe.
Therefore, most research in this area analyzes the most basic components for all known living things: RNA. It is a much simpler and more essential molecule than the best known DNA that defines how we bind.
“But RNA is even more complex than orders of magnitude, because one type of chemist is floating in space or clinging to the face of a lifeless planet.”
RNA is a polymer, which means that it is formed by chemical chains, in this case known as nucleotides. Given sufficient time, nucleotides can spontaneously bind to RNA due to chemical conditions.
The researchers are unaware of how a RNA polymerase has for a long time a self-replicating activity (RNA polymerase ribozyme) that arose from prebiotic conditions and then began to develop.
RNA molecules of less than 25 nucleotides do not show a specific function, but there is a reasonable expectation of finding a replicative ribozyme longer than 40-60 nucleotides.
RNA polymerase ribozyme has a length of 100 nucleotides so far in laboratory experiments.
“Current estimates suggest that the magic of 40 to 100 nucleotides in space space should not have been possible, which we consider an observable universe,” said Professor Totani.
However, the universe is more observable than it is. In contemporary cosmology, it is accepted that the universe is experiencing a period of rapid inflation that produces a vast field of expansion beyond the horizon.
And that we can observe directly. Factoring this excess into a model of pathogenesis increases the likelihood of life occurring.
Actually, there are about 1022 stars in the observable universe. Statistically, such an amount of matter should only be able to produce approximately 20 nucleotide RNA.
But thanks to rapid inflation, the Universe can contain more than 10100 stars, and if this is the case, more complex and life-sustaining RNA frameworks are more than just potential, they are virtually inevitable.
“Like many in this field of research, I am inspired by curiosity and big questions,” said Professor Totani.
