Rational Methods of DNA Synthesis, Exemplified for the Preparation of Parts of the Human Proopiomelanocortin Gene

Abstract Complete genes can now be prepared in single-batch procedures a) as one long oligonucleotide strand, b) as a number of simultaneously synthesized fragments. For further increase of overall efficiency DNA fragments terminated by a 3′-ribonucleoside can be joined by solid-phase single strand ligation using RNA ligase. This paper describes the application of these techniques to the preparation of parts of the human proopiomelanocortin gene.
