Non-complementary DNA helical structure induced by positive torsional stress.
We have induced a local conformational transition by positive torsional stress in small synthetic circular DNA molecules containing cruciforms with immobile or tetramobile branched junctions. The immobile species correspond to the extruded and intruded extrema of the tetramobile junction. Under normal conditions the sequences of all the branched species prevent them from being re-absorbed into ...
متن کاملModeling DNA thermodynamics under torsional stress.
Negatively twisted DNA is essential to many biological functions. Due to torsional stress, duplex DNA can have local, sequence-dependent structural defects. In this work, a thermodynamic model of DNA was built to qualitatively predict the local sequence-dependent mechanical instabilities under torsional stress. The results were compared to both simulation of a coarse-grained model and experimen...
متن کاملTransport of torsional stress in DNA.
It is well known that transcription can induce torsional stress in DNA, affecting the activity of nearby genes or even inducing structural transitions in the DNA duplex. It has long been assumed that the generation of significant torsional stress requires the DNA to be anchored, forming a limited topological domain, because otherwise it would spin almost freely about its axis. Previous estimate...
متن کاملThe Complementary Structure of Dna
This paper reviews very briefly the recent work on the “structure” of the sodium salt of desoxyribonucleic acid (DNA). By structure is meant not the chemical formula but the spatial arrangement of the atoms. The structure revealed by X-rays is the general structure-that is, the featmes common to DNA from different sources, since the X-rays only respond clearly to the repeating part of the struc...
متن کاملInfluence of DNA sequence on the structure of minicircles under torsional stress
The sequence dependence of the conformational distribution of DNA under various levels of torsional stress is an important unsolved problem. Combining theory and coarse-grained simulations shows that the DNA sequence and a structural correlation due to topology constraints of a circle are the main factors that dictate the 3D structure of a 336 bp DNA minicircle under torsional stress. We found ...
