This would occur, since the number of different bases in such an organism is a trade-off between a small number of bases increasing replication accuracy and a large number of bases increasing the catalytic efficiency of ribozymes.
Dette ville ske fordi antallet af forskellige baser i en sådanne organisme er en afvejning mellem et lille antal baser med bedre replikationspræcision og et stort antal baser med bedre katalytisk ribozymeffektivitet.
