Analysis of conventional and alternative CRISPR/Cas9 genome editing to enhance a single-base pair knock-in mutation

open access: yesBMC Biotechnology, 2021
Background The use of CRISPR/Cas9 technologies in generating single-base pair knock-in mutations has recently exploded in the number of methods available.

Influence of a fluorobenzene nucleobase analogue on the conformational flexibility of RNA studied by molecular dynamics simulations [PDF]

open access: yes, 2006
Chemically modified bases are frequently used to stabilize nucleic acids, to study the driving forces for nucleic acid structure formation and to tune DNA and RNA hybridization conditions.

Dynamics of a bubble formed in double stranded DNA

open access: yes, 2008
We study the fluctuational dynamics of a tagged base-pair in double stranded DNA. We calculate the drift force which acts on the tagged base-pair using a potential model that describes interactions at base pairs level and use it to construct a Fokker ...

Sequence-specific double-strand cleavage of DNA by penta-N-methylpyrrolecarboxamide-EDTA·Fe(II) [PDF]

open access: yes, 1983
In the presence of O2 and 5 mM dithiothreitol, penta-N-methylpyrrolecarboxamide-EDTA·Fe(II) [P5E·Fe(II)] at 0.5 µ M cleaves pBR322 plasmid DNA (50 µ M in base pairs) on opposite strands to afford discrete DNA fragments as analyzed by agarose gel ...

Self-organised criticality in base-pair breathing in DNA with a defect

open access: yes, 2011
We analyse base-pair breathing in a DNA sequence of 12 base-pairs with a defective base at its centre. We use both all-atom molecular dynamics (MD) simulations and a system of stochastic differential equations (SDE).

Lattice Attacks on Pairing-Based Signatures [PDF]

open access: yesInformation Security Journal: A Global Perspective, 2017
Practical implementations of cryptosystems often suffer from critical information leakage through side-channels (such as their power consumption or their electromagnetic emanations). For public-key cryptography on embedded systems, the core operation is usually group exponentiation – or scalar multiplication on elliptic curves – which is a sequence of ...

A Mathematical Model for RNA 3D Structures

open access: yesMathematics
The computational prediction of RNA three-dimensional (3D) structures remains a significant challenge, largely due to the limited understanding of RNA folding pathways.

Aviram-Ratner rectifying mechanism for DNA base pair sequencing through graphene nanogaps

open access: yes, 2012
We demonstrate that biological molecules such as Watson-Crick DNA base pairs can behave as biological Aviram-Ratner electrical rectifiers because of the spatial separation and weak hydrogen bonding between the nucleobases.

Modeling DNA Structure, Elasticity and Deformations at the Base-pair Level

open access: yes, 2003
We present a generic model for DNA at the base-pair level. We use a variant of the Gay-Berne potential to represent the stacking energy between neighboring base-pairs.

Thermodynamics of base pairing

open access: yesCurrent Opinion in Structural Biology, 1996
The study of the thermodynamics of base pairing is a rapidly expanding field due to its importance for taking advantage of opportunities presented by the growing database of nucleic acid sequences. Both natural and unnatural nucleic acids are being studied.
