title: Modern phosphotriester synthesis of long oligonucleotides and their use in genetic engineering.
abstract: Long oligodeoxyribonucleotides synthesized by the modern phosphotriester method, which is based on the use of O-nucleophilic intramolecular catalysis, were applied for the construction of artificial DNAs and directed mutagenesis of some genes.
