Absence of extended states in a ladder model of DNA [PDF]

open access: yes, 2006
We consider a ladder model of DNA for describing carrier transport in a fully coherent regime through finite segments. A single orbital is associated to each base, and both interstrand and intrastrand overlaps are considered within the nearest-neighbor ...

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

A Fair Power Allocation Approach to NOMA in Multi-user SISO Systems

open access: yes, 2017
A non-orthogonal multiple access (NOMA) approach that always outperforms orthogonal multiple access (OMA) called Fair-NOMA is introduced. In Fair-NOMA, each mobile user is allocated its share of the transmit power such that its capacity is always greater

The Influence of Neighboring Base Pairs upon Base-Pair Substitution Mutation Rates [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
The 2-aminopurine-induced transition, A·T → G·C, was studied at particular sites in bacteriophage T4 as a function of the nearby base-pair composition of the DNA. Changing a base pair changed the transition rate at the adjacent base pair up to 23-fold, and at the next base pair by a lesser amount.

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.

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.

Kostant-Lusztig $\mathbb A$-bases of Multiparameter Quantum Groups

open access: yes, 2018
We study the Kostant-Lusztig $\mathbb A$-base of the multiparameter quantum groups. To simplify calculations, especially for $G_2$-type, we utilize the duality of the pairing of the universal $R$-matrix.Comment: Submitted to Contemporary Math. on July 21,
