The inhibitory effect of D and L-polynucleotides of a given length (40-50n) on the catalytic activity of DNA polymerase β isolated from chromatin cells of acute myeloid leukemia HL-60 was evaluated. The synthesized L enantiomer was found to have a higher

Polydeoxyribonucleotides Pre-Clinical Findings in Bone Healing: A Scoping Review
Aim: Polydeoxyribonucleotide (PDRN) is a chain-like polymer derived from DNA. Recent in vitro and animal studies have showcased the beneficial impacts of PDRN on the process of bone mending, whether used on its own or in conjunction with other substances

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis
The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some ...

Carbethoxylation of Polynucleotides [PDF]
Diethyl pyrocarbonate has been shown to react with poly(A), poly(C) and poly(G) but poly(U) does not react. Diethyl pyrocarbonate appears to carbethoxylate amino groups on the bases. Poly(A) can bind one carbethoxy group per base but the binding capacity of poly(G) and poly(C) under non‐denaturing conditions is 0.32 and 0.23, respectively.

Kinetic studies on the phosphorolysis of polynucleotides by polynucleotide phosphorylase
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 ...

Molecular dynamics study on the mechanism of polynucleotide encapsulation by chitosan
The safe and effective delivery of therapeutic genes into target cell interiors is of great importance in gene therapy. Chitosan has been extensively studied as a gene delivery carrier due to its good biocompatibility and biodegradability.

Fast microwave heating-based one-step synthesis of DNA and RNA modified gold nanoparticles
Simple methods for attaching polynucleotides to gold nanoparticles are of interest for simplifying conjugation in a range of applications. Here, the authors report a microwave heating-based method for the fast, one-step attachment of a range of thiolated
