Synthetic DNA sequences have been proven viable in a study published this week by researchers led by a certain Steven Benner. Benner is the founder of the Foundation for Molecular Evolution Applied to Alachua, Floria. This study suggests that synthetic DNA with "unnatural" bases behaves much like natural DNA chains – blasting opens the way to the possibilities of chemical bonds in DNA outside of our basic understanding in G, C, A and T.
The new study includes four more letters or bases than those of guanine, cytosine, adenine and thymine, or G, C, A and T. Although this is not the first time that scientists are trying to scramble their own bases natural DNA in the mix, this is the first time that this is done successfully. This is the first time that bases other than those considered "natural" have been able to recognize and bind to each other.
This is the first time that it has been systematically proven that the double helix formed with these unnatural base bonds can retain their structure. The most recent basic combinations include S and B as well as P and Z.
Eight bases, four orthogonal pairs and a whole new set of synthetic systems that "meet the structural requirements necessary to support Darwinian evolution". According to the document, it is:
• Polyelectrolyte structural skeleton
• predictable thermodynamic stability
• Formation of stereoregular building blocks that respect Schrödinger aperiodic crystals
You remember that scene from The Fifth Element, right? The one where they took a disembodied hand and used it to build a human being in their own right. The science in the film was largely absurd, but I can not help but remember its content: "The compositional elements of its DNA chain are the same as ours – there are some simply no longer. Tightly packed with an infinite genetic knowledge. Almost as if this being was … conceived. "
They call this new search "hachimoji", in other words 8 letters. A bit like how "emoji" is essentially emotional letter, more or less. Measurement of thermodynamic parameters predicts stability – paper suggests that now, "hachimoji DNA [can] to increase the information density of natural terran DNA. In other words, we, the poor landless, have almost no potential for internal data storage space of this hachimoji company.
The abstract of the study suggested that "these results broaden the scope of molecular structures that support life, including life in the cosmos as a whole". It's time to take out the old paper from space and see if they forgot something they did not realize. could be looking!
