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 …

Sequence information can be obtained from single DNA molecules

I Braslavsky, B Hebert, E Kartalov… - Proceedings of the …, 2003 - National Acad Sciences
The completion of the human genome draft has taken several years and is only the
beginning of a period in which large amounts of DNA and RNA sequence information will be …

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 …

[7] Optical-trap force transducer that operates by direct measurement of light momentum

SB Smith, Y Cui, C Bustamante - Methods in enzymology, 2003 - Elsevier
Publisher Summary This chapter describes the optical-trap force transducer that operates by
the direct measurement of light momentum. By focusing a laser beam through a microscope …

Single-molecule kinetics of λ exonuclease reveal base dependence and dynamic disorder

AM Van Oijen, PC Blainey, DJ Crampton… - Science, 2003 - science.org
We used a multiplexed approach based on flow-stretched DNA to monitor the enzymatic
digestion of λ-phage DNA by individual bacteriophage λ exonuclease molecules. Statistical …

Ubiquitous transcriptional pausing is independent of RNA polymerase backtracking

KC Neuman, EA Abbondanzieri, R Landick, J Gelles… - Cell, 2003 - cell.com
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

AL Lucius, NK Maluf, CJ Fischer, TM Lohman - Biophysical journal, 2003 - cell.com
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 …

Protein synthesis by single ribosomes

F Vanzi, S Vladimirov, CR Knudsen, YE Goldman… - Rna, 2003 - rnajournal.cshlp.org
The ribosome is universally responsible for synthesizing proteins by translating the genetic
code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory …

Single-molecule detection of DNA hybridization

M Singh-Zocchi, S Dixit, V Ivanov… - Proceedings of the …, 2003 - National Acad Sciences
We demonstrate the detection of nanometer-scale conformational changes of single DNA
oligomers through a micromechanical technique. The quantity monitored is the …

Assembly of single chromatin fibers depends on the tension in the DNA molecule: magnetic tweezers study

SH Leuba, MA Karymov, M Tomschik… - Proceedings of the …, 2003 - National Acad Sciences
We have used magnetic tweezers to study in real time chaperone-mediated chromatin
assembly/disassembly at the level of single chromatin fibers. We find a strong dependence …
