The hypochromism of helical polynucleotides
Journal of Molecular Biology, 1962The hypochromism of the 260 mμ. absorption band of helical DNA is its lower absorbance, per base group, compared to the absorbance of the mononucleotides. The hypochromism of DNA has been calculated as a function pf the base composition and sequence. The oscillator strengths, transition monopoles and transition moments for the π→π* transitions of the ...

DNA end-processing enzyme polynucleotide kinase as a potential target in the treatment of cancer.
Future Oncology, 2010Pharmacological inhibition of DNA-repair pathways as an approach for the potentiation of chemo- and radio-therapeutic cancer treatments has attracted increasing levels of interest in recent years.

Polynucleotide Phosphorylase and the T3SS
2007Low temperatures as well as encounters with host phagocytes are two stresses that have been relatively well studied in many species of bacteria. The exoribonuclease polynucleotide phosphorylase (PNPase) has previously been shown to be required by several species of bacteria, including Yersinia, for low-temperature growth. We have shown that PNPase also

Selection and Darwinian evolution are phenomena which we commonly correlate to the existence of living organisms. When Charles Darwin about 130 years ago was working on his fundamental theory of biological evolution he had in mind highly developed organisms, plants and animals which he had studied for a lifetime.

Polynucleotide Polymorphism in Solution
Nature New Biology, 1971X-ray scattering experiments in solution show that poly dI.poly dC, poly (d(I-C). d(I-C)) and poly dG.poly dC have structures dissimilar to the A, B and C forms of DNA, while poly rI.poly rC is like the A′-RNA form.

The Synthesis of Oligo‐ and Polynucleotides
Angewandte Chemie International Edition in English, 1966AbstractProblems and results of the synthesis of oligonucleotides are reviewed. The central role of the nucleic acids in biochemistry is a challenge to synthesize nucleic acids of known base sequence and chain length. Oligomers with various sequences of up to 12 members and homo‐oligomers with a maximum chain length of 30 nucleotides can be obtained by
