The structure of B-helical C-G-A-T-C-G-A-T-C-G and comparison with C-C-A-A-C-G-T-T-G-G. The effect of base pair reversals.
The crystal structure of the DNA decamer C-G-A-T-C-G-A-T-C-G has been solved to a resolution of 1.5 A, with a final R-factor of 16.1% for 5,107 two-sigma reflections. Crystals are orthorhombic space group P2(1)2(1)2(1), with cell dimensions a = 38.93 A, b = 39.63 A, c = 33.30 A, and 10 base pairs/asymmetric unit. The final structure contains 404 DNA atoms, 142 water molecules treated as oxygen ...
متن کامل(G-H)*-C and G-(C-H)* radicals derived from the guanine.cytosine base pair cause DNA subunit lesions.
The radicals generated by the homolytic cleavage of an X-H bond from the guanine.cytosine (G.C) base pair were studied by using carefully calibrated theoretical methods. The gradient-corrected density functional B3LYP was applied in conjunction with double-zeta plus polarization and diffuse function basis sets. Optimized geometries, energies, and vibrational frequencies were obtained for all of...
متن کاملPseudo-complementary PNA actuators as reversible switches in dynamic DNA nanotechnology
The structural reorganization of nanoscale DNA architectures is a fundamental aspect in dynamic DNA nanotechnology. Commonly, DNA nanoarchitectures are reorganized by means of toehold-expanded DNA sequences in a strand exchange process. Here we describe an unprecedented, toehold-free switching process that relies on pseudo-complementary peptide nucleic acid (pcPNA) by using a mechanism that inv...
متن کاملA Novel PN Complementary Pair for Synchronization and Channel Estimation
In this paper, a novel pseudo-random noise complementary pair (PNCP) is proposed and adopted as the guard intervals in the time-domain synchronous OFDM (TDSOFDM) system. The proposed PNCP has nearly ideal aperiodic auto-correlation property and inherits the differential property of the PN sequence. Simulations demonstrate the proposed TDSOFDM system padded with PNCP could achieve better perform...
متن کاملComplementary base-pair-facilitated electron tunneling for electrically pinpointing complementary nucleobases.
Molecular tips in scanning tunneling microscopy can directly detect intermolecular electron tunneling between sample and tip molecules and reveal the tunneling facilitation through chemical interactions that provide overlap of respective electronic wave functions, that is, hydrogen-bond, metal-coordination-bond, and charge-transfer interactions. Nucleobase molecular tips were prepared by chemic...
