Abstract
Promoter sequences were studied by cluster analysis, Five regions with nonrandom base distribution were found, and their typical structural elements were revealed, Some of these elements were homologous to the sequences located near the promoter regions, which, in a complex with RNA polymerase, displayed hypersensitivity to DNase I. Since near such sites the enzyme tightly contacts the promoter DNA, the physicochemic al features of the found sequences may determine the specificity of th e interaction of RNA polymerase with different promoters.
