The polynucleotide kinase reaction was used in analyses of complex mixtures of oligodeoxynucleotides which were fractionated by various two-dimensional nucleotide ;mapping' procedures. Parallel ionophoretic analyses on DEAE-cellulose paper, pH2, and AE-cellulose paper, pH3.5, of venom phosphodiesterase partial digests of 5'-terminally labelled oligonucleotides enabled the sequence of the nucleotides to be deduced uniquely. A ;diagonal ionophoresis' method has been used with mixtures of nucleotides. Application of these methods to 5'-terminally labelled DNA from bacteriophage lambda gave the terminal sequences pA-G-G-T-C-G and pG-G-G-C-G. Identical 5'-terminal sequences were found with DNA from bacteriophage 424.
