Die Botschaft von LUCA – der letzte universelle gemeinsame Vorfahre


The standard genetic code is the only reliable information about the
firstliving cell on Earth called the last universal common ancestor –
LUCA. The central mystery of the genetic code is the assignment of the canonical amino acids to the codons – base triplets. Simple and uni­
form combinatorial rules indicate that the standard genetic code arose during the fusion of four primordial single base­pair codes.
