<Protein biosynthesis> occurs in nature with frequency error better than 10-4. Regulation of <polypeptide synthesis> is caused by several factors. Recently the effect of <antisense oligonucleotides> on <peptide synthesis> in vivo as well as in vitro has been presented. The specific recognition of substrate by ribozyme is also determined by sense-antisense hybridization reaction of ribozymes flanking sequences.
