When compared to DNA, poly(dA)·poly(dT) was found to have a smaller pitch (by about 0.5 base pair/turn), whereas poly(dA-dT)·poly(dA-dT) has a slightly larger pitch (by 0.1 base pair/turn). These features correlate well with the known ability of the alternating copolymer to ...
The concave surface between the arms is exactly complementary to the right-handed double helix of DNA in the B-form. These arms interact with the duplex through intercalation between the base pairs ( 30 ). Intercalation results in a change in helical pitch of the duplex, which leads to ...
While being a relatively subtle effect, even small changes in DNA twist can play important roles, for example for the pitch and curvature of higher-order DNA origami structures (79–81). In addition, the delocalized and temporary basepair breaks revealed by the simulations might well serve as ...
When compared to DNA, poly(dA) · poly(dT) was found to have a smaller pitch (by about 0.5 base pair/turn), whereas poly(dA-dT) · poly(dA-dT) has a slightly larger pitch (by 0.1 base pair/turn). These features correlate well with the known ability of the alternating copolymer ...
Depending on the number of base pairs involved in one turn of the tube, the population of left-/right-handed and short/long tubes changed. The bending stress caused by the stiffness of the bundled double helices and the non-natural helical pitch determine the structural variety of the tubes....

To solve the question regarding how many base pairs are contained in each helical turn of B-DNA, we can follow these steps:1. Understand the Structure of B-DNA: - B-DNA is one of the most common forms of DNA in cells. It is

In particular, the effect of height, apex radius, and degree of exponential tapering on ellipticity, cross polarization rejection, and reflection coefficient is investigated.关键词: helical antennas apex radius cross polarization rejection exponential tapering helical antennas pitch angle reflection ...
Our data, which combine multifrequency imaging and Fourier analysis, confirm the structure deduced from averaging techniques (XRD, cryoEM) for surface features of single virus particles, down to the helical pitch of the coat protein subunits, 2.3 nm. Remarkably, multifrequency AFM images do ...
