This invention provides an apparatus and method for analyzing a polynucleotide sequence;either an unknown sequence or a known sequence. A support, e.g. a glass plate, carries an array the whole or a chosen part a complete set oligonucleotides which are capable taking part in hybridization reactions. The array may comprise one or more pair oligonucleotides chosen lengths. The polynucleotide sequence, or fragments there, are labelled and applied to the array under hybridizing conditions. Applications include analyses known point mutations, genomic fingerprinting, linkage analysis, characterixation mRNAs, mRNA populations, and sequence determination. 5700639 METHOD
