Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

open access: yes, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

Archaea: A Gold Mine for Topoisomerase Diversity

open access: yesFrontiers in Microbiology, 2021
The control of DNA topology is a prerequisite for all the DNA transactions such as DNA replication, repair, recombination, and transcription. This global control is carried out by essential enzymes, named DNA-topoisomerases, that are mandatory for the ...

Topological entropy of DNA sequences [PDF]

open access: yesBioinformatics, 2011
Abstract Motivation: Topological entropy has been one of the most difficult to implement of all the entropy-theoretic notions. This is primarily due to finite sample effects and high-dimensionality problems. In particular, topological entropy has been implemented in previous literature to conclude that entropy of exons is higher than of ...

DNA topology: Topological transformation of DNA by reaction of cisplatin-DNA-core histone complexes with human DNA topoisomerase [PDF]

open access: yesNucleic Acids Symposium Series, 2002
Cis-diamminedichloroplatinium(II), an active antitumor agent binds to core-histone -SV40 DNA complexes prepared by reaction of DNA with core-histone, and alters the fiber-like structure into the loosened structure. In order to model the cisplatin-modified chromatin complexes in cell, the complexes were reacted with human DNA topo II.

Physical Characterization of Gemini Surfactant-Based Synthetic Vectors for the Delivery of Linear Covalently Closed (LCC) DNA Ministrings. [PDF]

open access: yesPLoS ONE, 2015
In combination with novel linear covalently closed (LCC) DNA minivectors, referred to as DNA ministrings, a gemini surfactant-based synthetic vector for gene delivery has been shown to exhibit enhanced delivery and bioavailability while offering a ...

Biologic [PDF]

open access: yes, 2002
In this paper we explore the boundary between biology and the study of formal systems (logic). In the end, we arrive at a summary formalism, a chapter in "boundary mathematics" where there are not only containers but also extainers >

TEX264 coordinates p97- and SPRTN-mediated resolution of topoisomerase 1-DNA adducts

open access: yesNature Communications, 2020
Eukaryotic topoisomerase 1 (TOP1) regulates DNA topology to ensure efficient DNA replication and transcription. Here, the authors reveal insights into the molecular resolution of topoisomerase 1-DNA adducts by TEX264, p97 and SPRTN.

A new topology of the HK97-like fold revealed in Bordetella bacteriophage by cryoEM at 3.5 A resolution. [PDF]

open access: yes, 2013
Bacteriophage BPP-1 infects and kills Bordetella species that cause whooping cough. Its diversity-generating retroelement (DGR) provides a naturally occurring phage-display system, but engineering efforts are hampered without atomic structures.
