Abstract  The energy of interaction between DNA strands in promoters is of great functional importance. Visualization of the energy of DNA strands distribution in promoter sequences was achieved. The separation of promoters in groups by their energetic properties enables evaluation of the dependence of promoter strength on the energetic properties. The analysis of groups (clusters) of promoters distributed by the energy of DNA strands interaction in −55, −35, −10 and +6 sequences indicates their connection with the transcriptional activity.

Key words： DNA sequence      Promoter strength      DNA chains interaction energy      DNA sequences classification
