Theory of the origin of protobiopolymers.

What are Protobiopolymers
Protobiopolymers are molecules that for the first time showed signs of living organisms in a primitive form, or rather one – the ability to self-doubling. They are the original versions of modern polymers.

Biopolymers include:


According to the latest data from microbiochemistry scientists, the first such molecule was RNA, and not protein or DNA, as was previously accepted.

After the molecules were able to copy themselves, this formed the basis for reproduction and the molecule was no longer limited by the time of the chemical existence of the molecule, but “cloned” itself. There are several theories about the origin of protobiopolymers:

Adsorption theory;
Low temperature theory;
Coacervate theory.

The essence of the theories of the formation of protobiopolymers
The first theory is based on the thermosynthesis of polymers at high temperatures. In the conditions of the ancient atmosphere, the temperature of the atmosphere was high, which means that the molecules could “stick together” under the influence of high temperatures. Subsequently, the formed molecules retained the acquired properties under the changed conditions.

The second theory is based on the selective combination of certain molecules. There are intermolecular forces of interactions (for example, electrochemical attraction, underlying the formation of a peptide bond in a protein molecule), which attract certain ends of the molecules to each other and repel others, which could lead to the formation of polymers.

Proponents of the third theory, in contrast to the first, argue that the source of energy was cold plasma. Its source were thunderstorms (their frequency during the formation of the planet was much higher) and the aurora, this theory has laboratory confirmation.

The latter theory is based on the fact that biopolymer molecules, collecting water around them, form semi-permeable capsules that selectively accumulate individual substances and do not allow others to pass through, but this theory does not explain the appearance of biopolymers themselves, but only their further transformation into a cell.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
