ABSTRACT:
A method is provided of making an oligonucleotide which comprises hybridizing (a) a shorter fragment of the desired oligonucleotide with (b) a nucleic acid fragment longer than (a) and complementary to the desired oligonucleotide, one of (a) and (b) is linked to an organic radical which differentiates its physical properties relative to the other of (a) and (b), contacting the hybridized material with an enzyme and nucleoside triphosphates whereby the shorter fragment is extended in one direction until it is substantially coterminal with the complementary nucleic acid fragment, denaturing the hybridized material and separating lengthened (a) from (b).
