Ten years of tension: single-molecule DNA mechanics
C Bustamante, Z Bryant, SB Smith - Nature, 2003 - nature.com
The basic features of DNA were elucidated during the half-century following the discovery of
the double helix. But it is only during the past decade that researchers have been able to …

Stretching DNA and RNA to probe their interactions with proteins
JF Allemand, D Bensimon, V Croquette - Current opinion in structural …, 2003 - Elsevier
When interacting with a single stretched DNA, many proteins modify its end-to-end distance.
This distance can be monitored in real time using various micromanipulation techniques that …

Ubiquitous transcriptional pausing is independent of RNA polymerase backtracking
Abstract RNA polymerase (RNAP) transcribes DNA discontinuously, with periods of rapid
nucleotide addition punctuated by frequent pauses. We investigated the mechanism of …

General methods for analysis of sequential “n-step” kinetic mechanisms: application to single turnover kinetics of helicase-catalyzed DNA unwinding
Helicase-catalyzed DNA unwinding is often studied using" all or none" assays that detect
only the final product of fully unwound DNA. Even using these assays, quantitative analysis …
