“This invention can Make a revolution understanding of this biological field,” the scientists said University of Oxford After discovering a living Unique DNA.
The study was published in a special issue Public Library of ScienceTechniques used, their development and results are explained.

He Oligohymenophoria sp. PL0344 It is a type of protist Eukaryotic cells Not included in the best-known species of such organisms Animals, plants and fungi. According to the authors, their DNA behaves differently from all others.
Before delving deeper, it is important to keep some basic concepts in mind chains Defines cellular behavior: The key codons that make it up are 4 nucleotides: Adenine (A), Cytosine (C), Thymine (D) and Guanine (G). They are organized Three groups Traditional genetics read instructions to synthesize proteins and carry out other cellular processes.
But the protist studied by scientists does not obey this natural law: it has its own codes for coordination. The amino acids are lysine and glutamic acid.

This discovery allows us to ask the questions: How did it evolve to the point where it could change all chains and protein synthesis? Can protists have other genetic changes?
“There are still genetic code rearrangements unexplored waiting to be discovered,” said the Oxford experts.
“An additional row Ciliates (Revolutionaries) Prototype and others Eukaryotes microorganism “It will reveal the most diverse changes in the genetic code, helping to understand the evolution and mechanisms of the genetic code,” they concluded.
