Peskin Comments: 12 pages, 4 figures Subj-class: Biomolecules; Subcellular Processes \\ A chemical kinetic model of the elongation dynamics of RNA polymerase along a DNA sequence is introduced. Unlike previous models that attempt to explain the motion of RNA polymerase using internal strain and stresses, we propose a chemical kinetic model which governs the discrete movement of the RNA polymerase along a DNA tether, with no consideration given to elastic effects. The model's novel concept is a ``look-ahead'' feature, in which nucleotides bind reversibly to the DNA prior to being incorporated covalently into the nascent RNA chain. Results are presented for specific DNA sequences that have been used in single-molecule experiments of the random walk of RNA polymerase along DNA. \\ ( http://arXiv.org/abs/q-bio/0603012 , 77kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% %%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%--- -- Roeland Merks Department of Plant Systems Biology VIB / Ghent University Technologiepark 927 B-9052 Ghent, Belgium http://www.psb.ugent.be Tel. +32-(0)9-33 13825 email: post@roelandmerks.nl http://www.roelandmerks.nl weblog: http://biolog.volkskrantblog.nl
