Escherichia coli DNA Pribow and Transcription Initiation Sites A Statistical Study

In this paper,a statistical study of PRIBOW and transcription initiation sites in E.coli DNA protein-coding genes was presented.The range over which the two signal sequences extend was assessed,and their information content was evaluated.The results were compared with those obtained from"HUMAN"samples.Statistically significant difference were found for both signals,and were especially for corresponding to the transcription initiation site.
