Abstract
Summary The published translation termination sequences have been compiled and analysed to aid the interpretation of experiments on termination codon usage in the Xenopus oocyte (Bienz et al. 1981). There are significant differences between prokaryotes and eukaryotes concerning the usage of the three termination codons and of tandem stops. In addition viruses show termination strategies that differ from those of their hosts. Preferred context sequences flanking termination codons are described. Contexts vary within the last codon according to the nature of the termination codon, but are uniform within the first triplet following the terminators.
