It's mathematically unlikely that only right-handed nucleotides would be added time after time without a single left-handed one being added. Sooner or later an incorrect, left-handed nucleotide would be added. While proteins could be either right or left handed, there is only one "hand" in any given protein molecule. It just so happens that a right handed one happened to have an interesting property first. It's not a question of statistics, once a right-handed protein appeared that started eating up the primordial soup the race was over before the left handed ones had a chance. Remember, when these proteins replicate is not via Star-Trek replicators, they actually consume the other amino acids in the primordial soup. TP
