Quantification bias caused by plasmid DNA conformation in quantitative real-time PCR assay. [PDF]
PLoS ONE, 2011 Quantitative real-time PCR (qPCR) is the gold standard for the quantification of specific nucleic acid sequences. However, a serious concern has been revealed in a recent report: supercoiled plasmid standards cause significant over-estimation in qPCR ...

The cellular protein nucleolin preferentially binds long-looped G-quadruplex nucleic acids [PDF]
, 2017 open5noBACKGROUND: G-quadruplexes (G4s) are four-stranded nucleic acid structures that form in G-rich sequences. Nucleolin (NCL) is a cellular protein reported for its functions upon G4 recognition, such as induction of neurodegenerative diseases, tumor

Protein-DNA interactions: statistical analysis of interatomic contacts in major and minor grooves
Вавиловский журнал генетики и селекции, 2018 The interactions between protein and DNA in essence underlie all processes in a living cell. Understanding the principles of specific recognition of DNA sites will open the way to understand how these processes are controlled and to interfere in their ...

Structural visualization of key steps in human transcription initiation. [PDF]
, 2013 Eukaryotic transcription initiation requires the assembly of general transcription factors into a pre-initiation complex that ensures the accurate loading of RNA polymerase II (Pol II) at the transcription start site. The molecular mechanism and function

Conformational classification of functional nucleic acids [PDF]
Nucleic Acids Symposium Series, 1999 The kink parameters would provide the tolerant aspect for irregular helical structure of nucleic acid. Using these kink parameters, the classification of conformation space was carried for the functional nucleic acid molecules. The kink parameters could afford us the simple structural aspects about the constructive parts of functional molecules.

Structure of d(TGCGCA)(2) and a comparison with other DNA Hexamers [PDF]
, 1998 The X-ray crystal structure of d(TGCGCA)(2) has been determined at 120 K to a resolution of 1.3 Angstrom. Hexamer duplexes, in the Z-DNA conformation, pack in an arrangement similar to the 'pure spermine form' [Egli et al. (1991). Biochemistry, 30, 11388-
