Phylogenetic, phylogeographic and divergence time analysis of Anopheles subpictus species complex using ITS2 and COI sequences

open access: yesAsian Pacific Journal of Tropical Medicine
To address the phylogenetic and phylogeographic relationship between different lineages of Anopheles (An.) subpictus species complex in most parts of the Asian continent by maximum utilization of Internal Transcriber Spacer 2 (ITS2) and cytochrome C ...

Localization of Denaturation Bubbles in Random DNA Sequences [PDF]

open access: yes, 2003
We study the thermodynamic and dynamic behaviors of twist-induced denaturation bubbles in a long, stretched random sequence of DNA. The small bubbles associated with weak twist are delocalized.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

DNA amplified fingerprinting, a useful tool for determination of genetic origin and diversity analysis in Citrus [PDF]

open access: yes, 1995
We used three short repetitive nucleotide sequences [(GTG)5, (TAC)5, and (GACA)4] either as radiolabeled probes for hybridization with restricted Citrus DNA or as single primers in polymerase chain reaction amplification experiments with total genomic ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Contribution to the phylogeny of Microgastrinae (Hymenoptera: Braconidae) based on mitochondrial COI and nuclear 28S rDNA genes, with comments on the identity of Pholetesor circumscriptus (Nees, 1834) [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
Microgastrines are diverse group of endoparasitoid wasps attacking caterpillars (Lepidoptera). Despite their importance in biological control, there is still no consensus concerning the phylogeny relationships among taxa.

Genomics dataset of unidentified disclosed isolates

open access: yesData in Brief, 2016
Analysis of DNA sequences is necessary for higher hierarchical classification of the organisms. It gives clues about the characteristics of organisms and their taxonomic position. This dataset is chosen to find complexities in the unidentified DNA in the

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

On the nucleotide distribution in bacterial DNA sequences [PDF]

open access: yes, 2010
It is probable that the distributional structure of DNA sequences arises from the accumulation of many successive stochastic events such as nucleotide deletions, insertions, substitutions and elongations [1, 2, 3, 4, 5, 6, 7].
