Georgia - molecules turned out to be a clue to trace the evolution of the biological roots.
Experts from Georgia Institute of Technology have learned that life on earth has a common ancestor, since 3.8 billion years, and traces of 'fingerprint' of life in the early days of get carried away by all the cells alive today.
Reported the Daily Mail, this NASA-funded research will not only help researchers study how life originated on Earth, but also help identify extraterrestrial environments where life begins.
Professor Loren Williams of the Georgia Tech School of Chemistry and Biochemistry led the first research on the molecular association, called the ribosome. Collections of molecules that is what leads to the formation of life.
Ribosome protein contained in the cell possessed on this earth, and serves to change the genetic information from RNA.
However, being in the early days of life does not carry the protein, so by studying protein-free part of the ribosome, scientists were able to discover the oldest chemical processes.
Using a technique called Structural Comparative Method, researchers were able to create a model of the ribosome with quite detailed.
By way of distorting techniques, and 'play back' ribosomal recording, researchers said they had uncovered the secrets of creation and 'answer the existential questions about our existence in the universe.'
Meanwhile, additional research on the ribosome revealed the 'molecular fingerprint' which shows how molecules grow.
Professor Williams compares the growth process of the trunk, where the new circle increases in the outer layer, but the center has not changed. Meanwhile, the central part of the stem represents the tree of life.
Just as the central part of the tree has not changed every year, all of the ribosome that exist in today's life contains the core parts are the same since 3.8 billion years ago.
"We're trying to figure out how to read the oldest recorded biology, to understand the process of pre-biological origin of life and evolution of life on Earth," said Professor Williams.
"Ribosome has a recording its own history. This molecule enlarges every time, but part of his oldest frozen like tree rings."
The record shows how biology has changed over billions of years. Also could be an indication of environmental conditions in which the earth evolved biology, and help inform the search for life elsewhere in the universe.
The research attracted the attention of NASA astrobiologist in the researcher's life on another planet, where biological processes can occur.
"The most central core of the ribosome older than biology, produced by the process of evolution that we ourselves do not quite understand," added Professor Williams.
"Ribosome is also one of the main targets for antibiotics, so studying its biological architecture and can be very profitable."
"This work allows us to look back at the roots of the tree of life, the ancestor of all modern cells, the time in which proteins and nucleic acids has not been the base for all of biochemistry," said Carl Pilcher, director of NASA's Astrobiology Institute while.
"It helps us understand the earliest stages of the development of life on earth, and can guide our search for extraterrestrial environments where life may thrive."
The study, published in the journal Proceedings of the US National Academy of Sciences.
