Investigation of a new conformation of double stranded DNA
C. Limouse, C. Danilowicz, V. W. Coljee +2
It had been proposed that overstretching double stranded DNA from the 5-5 ends will produce a new fiber form of dsDNA that is narrower than the S form that has been suggested to re…
Pause Point Spectra in DNA Constant-Force Unzipping
J. D. Weeks, J. B. Lucks, Y. Kafri +3
Under constant applied force, the separation of double-stranded DNA into two single strands is known to proceed through a series of pauses and jumps. Given experimental traces of c…
Measurement of the Phase Diagram of DNA Unzipping in the Temperature- Force Plane
C. Danilowicz, Y. Kafri, R. S. Conroy +3
We separate double stranded lambda phage DNA by applying a fixed force at a constant temperature ranging from 15C to 50C, and measure the minimum force required to separate the two…
DNA unzipped under a constant force exhibits multiple metastable intermediates
Claudia Danilowicz, Vincent W. Coljee, Cedric Bouzigues +3
Single molecule studies, at constant force, of the separation of double-stranded DNA into two separated single strands may provide information relevant to the dynamics of DNA repli…
