Is UAA or UGA part of the recognition signal for ribosomal initiation?
In none of the 92 published prokaryotic sequences is a translation codon preceeded by UAG as the first "termination codon". In most cases the UAA or UGA is close to the initiation codon and may be part of the ribosome recognition signal.
