Unusual Nucleic acid nanostructures based on G-quadruplex DNA

open access: yesACI Avances en Ciencias e Ingenierías, 2015
A nano-assembly based on non-canonical DNA structures is reported. For the nanofabrication of a DNA-based structure the self-assembly of guanine quadruplex (Hoogsteen base pairing) and double-stranded DNA (Watson-Crick base pairing) was exploited.

The General Pair-based Weighting Loss for Deep Metric Learning [PDF]

open access: yesarXiv, 2019
Deep metric learning aims at learning the distance metric between pair of samples, through the deep neural networks to extract the semantic feature embeddings where similar samples are close to each other while dissimilar samples are farther apart.

Highly specific unnatural base pair systems as a third base pair for PCR amplification [PDF]

open access: yesNucleic Acids Research, 2011
Toward the expansion of the genetic alphabet of DNA, we present highly efficient unnatural base pair systems as an artificial third base pair for PCR. Hydrophobic unnatural base pair systems between 7-(2-thienyl)imidazo[4,5-b]pyridine (Ds) and 2-nitro-4-propynylpyrrole (Px) were fine-tuned for efficient PCR, by assessing the amplification efficiency ...

Teaching the Central Dogma of Molecular Biology using Jewelry

open access: yesJournal of Microbiology & Biology Education, 2012
”Cracking the Code” is an activity developed to demonstrate the processes of transcription and translation. This hands-on activity helps students understand the relationship between form (base pairing) and function (information storage and transfer) of ...

Factor-4 and 6 compression of cyclotomic subgroups of and

open access: yesJournal of Mathematical Cryptology, 2010
Bilinear pairings derived from supersingular elliptic curves of embedding degrees 4 and 6 over finite fields 𝔽2m and 𝔽3m, respectively, have been used to implement pairing-based cryptographic protocols.

Spontaneous formation and base pairing of plausible prebiotic nucleotides in water

open access: yesNature Communications, 2016
One of the questions for prebiotic chemistry is the formation of complementary base pairing systems. Here, the authors show that plausible two prebiotic heterocycles can form glycosidic bonds with ribose in water and that these spontaneously base-pair in

Pairing symmetry in BiS$_{2}-$based superconductors [PDF]

open access: yesarXiv, 2013
The possible pairing symmetries for BiS$_{2}-$based superconductors is investigated by using a minimal two-orbital model with onsite and nearest-neighbor intraorbital attractions $V_{0}$ and $V_{1}$, respectively. By using the mean-field approximation and solving the self-consistent equations, the phase diagram of the pairing symmetry is obtained.

DNA-Directed Base Pair Opening [PDF]

open access: yesMolecules, 2012
Strand separation is a fundamental molecular process essential for the reading of the genetic information during DNA replication, transcription and recombination. However, DNA melting in physiological conditions in which the double helix is expected to be stable represents a challenging problem.

Selective prebiotic conversion of pyrimidine and purine anhydronucleosides into Watson-Crick base-pairing arabino-furanosyl nucleosides in water

open access: yesNature Communications, 2018
Arabinonucleic acid (ANA) Watson-Crick base-pair with RNA/DNA and can evolve to display enzyme-like function. Here, the authors now identify a prebiotic pathway that yields the complete set of Watson-Crick base-pairing purine and pyrimidine ANA ...

Covering All the Bases in Genetics: Simple Shorthands and Diagrams for Teaching Base Pairing to Biology Undergraduates

open access: yesJournal of Microbiology & Biology Education, 2011
Explaining base pairing is an important element in teaching undergraduate genetics. I propose a teaching approach that aims to close the gap between the mantra “A pairs with T, and G pairs with C” and the “intimidating” chemical diagrams.
