    摘要: A method of synthesizing double-stranded DNA sequences is disclosed. The method comprises the steps of:

    (a) preparing a first series of oligodeoxyribo­nucleotide fragments which, when joined in proper sequence, form a DNA coding strand;
    (b) preparing a second series of oligodeoxyribo- nucleotide fragments which, when joined in proper sequence, form a DNA strand complementary to the coding strand;
    (c) compelling hydrogen bonding and ligation in proper sequence between the first and second series of oligodeoxyribonucleotide fragments prepared in steps (a) and (b) in a single reaction to produce the entire double-stranded DNA sequence;
    (d) treating the double-stranded DNA sequence with one oligonucleotide primer for each strand under hybridizing conditions;
    (e) polymerizing an extension product of each primer that is complementary to each strand of the double-stranded DNA sequence which is a template for forming the primer extension product;
    (f) denaturing the product of step (e) to separate the primer extension products from their respective templates to form four separate single-­stranded DNA sequences;
    (g) treating the denatured product of (f) with oligonucleotide primers, such that a primer extension product is synthesized using each of the single strands produced in step (f) as a template resulting in amplification of the double-stranded DNA sequence; and
    (h) repeating steps (d), (e), (f) and (g) until the desired quantity of the double-stranded DNA sequence is formed.
