A study was made of the potentialities of DNA sequencing by hybridizat
ion with oligonucleotide matrix (SHOM) in the version of contiguous st
acking hybridization on gapped matrices. The reconstruction efficacy w
as assessed for various combinations of matrices and l-oligonucleotide
libraries. It was shown that contiguous stacking hybridization on gap
ped matrices allows the number of additional hybridizations to be cut
down by half without loss of reconstruction efficacy.
