Una nuova forma di Dna sintetico è stata testata negli Usa. Si tratta di un sistema che estende l’alfabeto genetico da 4 a 8 lettere. Il Dna ‘monster’ è protagonista di uno studio pubblicato su ‘Science’, con cui gli autori, Shuichi Hoshika e colleghi, hanno dimostrato la capacità di raddoppiare la densità di informazioni nel codice della vita…Continua su AdnKronos>>

For The First Time, Scientists Have Made Synthetic DNA With 4 Additional Letters
Earth might have a dizzying array of life forms, but our biology ultimately remains a solitary data point – we simply don’t have a reference for life based on DNA different from our own. Now, scientists have taken matters into their hands to push the boundaries on what life could be like.
Research funded by NASA and led by the Foundation for Applied Molecular Evolution in the US has led to the creation of an entirely new flavour of the DNA double helix, one that has an additional four nucleotide bases.
It’s being called hachimoji DNA (from the Japanese words for ‘eight letters’) and it includes two new pairs to add to the existing partnerships of adenine (A) paired with thymine (T), and guanine (G) with cytosine (C)….Continua su Sciencealert>>
