Binding of phenazinium dye safranin T to polyriboadenylic acid: spectroscopic and thermodynamic study. [PDF]
PLoS ONE, 2014 Here, we report results from experiments designed to explore the association of the phenazinium dye safranin T (ST, 3,7-diamino-2,8-dimethyl-5-phenylphenazinium chloride) with single and double stranded form of polyriboadenylic acid (hereafter poly-A ...

Dependence of the nature of the Holstein polaron motion in a polynucleotide chain subjected to a constant electric field on the initial polaron state and the parameters of the chain [PDF]
, 2021 In this work, we consider the motion of a polaron in a polynucleotide Holstein molecular chain in a constant electric field. It is shown that the character of the polaron motion in the chain depends not only on the chosen parameters of the chain, but also on the initial distribution of the charge along the chain.

When DNA Polymerases Multitask: Functions Beyond Nucleotidyl Transfer
Frontiers in Molecular Biosciences, 2022 DNA polymerases catalyze nucleotidyl transfer, the central reaction in synthesis of DNA polynucleotide chains. They function not only in DNA replication, but also in diverse aspects of DNA repair and recombination.

An onset model of mutually catalytic self-replicative systems formed by an assembly of polynucleotides [PDF]
, 2023 Self-replicability is the unique attribute observed in all the living organisms and the question how the life was physically initiated could be equivalent to the question how self-replicating informative polymers were formed in the abiotic material world.

Use of template switching for DNA synthesis [PDF]
, 2012 A method of preparing a DNA copy of a target polynucleotide using template switching is described. The method includes mixing a double stranded template/primer substrate made up of a DNA primer oligonucleotide associated with a complementary ...

Kinetic studies on the phosphorolysis of polynucleotides by polynucleotide phosphorylase
Journal of Biological Chemistry, 1975 The kinetics of the phosphorolysis of polynucleotide (as differentiated from oligonucleotide) by polynucleotide phosphorylase of Micrococcus luteus has been investigated. Double reciprocal plots of initial velocity against either inorganic phosphate or polynucleotide concentration are linear, and furthermore, the affinity of the enzyme for either ...

Driven translocation of a polynucleotide chain through a nanopore--A continuous time Monte-Carlo study [PDF]
Physical Review E74, 011911 (2006), 2006 Using continuous time Monte-Carlo method we simulated the translocation of a polynucleotide chain driven through a nanopore by an electric field. We have used two models of driven diffusion due to the electric field. The chain may have strong interaction with the pore, and depends on which end of the chain first enters the pore.

A Raman spectroscopic study of the interaction between nucleotides and the DNA binding protein gp32 of bacteriophage T4 [PDF]
, 1987 Raman spectra of the bacteriophage T4 denaturing protein gp32, its complex with the polynucleotides poly(rA), poly(dA), poly(dT), poly(rU), and poly(rC), and with the oligonucleotides (dA)8 and (dA)2, were recorded and interpreted.
