Before life begins on Earth, there are a large number of chemicals in the environment that interact with each other randomly or less, and it is not clear how the chemical mess can cause the complexity of cells.
Now, a team led by Tony J. Jia of the Tokyo Institute of Technology and Cohn Chandro of the National University of Malaysia said that ordinary alpha hydroxide acids, such as glycolic acid and lactic acid, are effortlessly self-assembled in small polymer solutions and dehydrated after dehydration in moderate temperatures.
It must have happened in the primitive beaches and river banks, or in dried ponds. It is a new type of cell that can capture and concentrate nucleic acids and proteins such as biomolecule.
Unlike most modern cells, these drops are able to easily integrate and repair, and thus can host genetic and metabolic systems that are potentially very early to be necessary for the property of life.
All life cells on Earth are made of. Cells are made from fat, protein and nucleic acids, where fat is made up of a cell membrane, a coat that keeps the other components together and responds to the environment, and exchanges food and waste.
How complex cells formed in the core such as complex molecular assembly have remained a mystery.
Most of the research properties of life focus on the fact that how the molecules and structures of life are produced by the environment, then synthesized in the structures which leads to the first cells.
It is possible, however, that many other types of molecules were formed along with biological molecules on the early Earth, and it is possible that life began with a very simple chemistry, which has no connection with modern biomolecules, Do not give up, and then evolved rapidly with complex steps. For the emergence of structures in modern cells.
The previous work in ELSI showed that the alpha-hydroxy acid found in meteorites and many biochemistry transmits light organic compounds of simple organic compounds known as simulations to the mixture of long polysters automatically.
That these composite polyester systems formed a phase and gathered on the reorganization of the structure like the intuitive cell structures.
The most difficult aspect of this work was to create new ways of describing the properties and functions of droplets, because no one has previously analyzed these systems.
Jia said that the team was fortunate that there was a diversity in this field of multidisciplinary expertise, including chemists, biochemists, material scientists and geologists.
They first measured the stability of these structures and found that they can live for a very long time based on environmental conditions, but they can also be combined and consolidated.
They then tested the ability to separate the molecules from the environment of these structures and found that they gathered large dye molecules.
He then showed that these drops can host RNA and protein molecules and allow them to be functionally activated for the date of the catalyst.
Apart from this, the team showed that the droplets can help to make a lipid layer on its surface, suggesting that they can be helped in the formation of primary cell shed.
Jia and her colleagues are not convinced that these structures are the ancestors of direct cells, but believe that these drops may have enabled the combination of primary cells on the ground.
He noted that the new partition system he found was very simple and could be easily created in the primitive atmosphere throughout the universe.
“This allows us to visualize non-biological systems on early ground, which can be one hand in the origin of life, suggesting that there may be many other non-biological systems to investigate such a future. “Jia says,” Jia says.
They believe that such models can allow the development of systems or better studies of the development of various chemical systems of those that represent the possibility of the existence of complex chemistry in primitive planetary bodies.
“The early earth was definitely a chaotic place,” says Jia, “and most life studies often focus on modern biomolecules in relatively” clean “situations. Interesting structures can be generated by themselves.” The author now admits T is growing systematically.
