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.

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

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

Nucleotide and polynucleotides
2012To enhance the efficiency for oligonucleotide chain extension, Sekine has developed the 4-methoxytritylthio- MMTrS group for the protection of the 5′-hydroxyl group in the 3′-O-TBDMS- deoxycytidine, deoxyadenosine and deoxyguanosine with appropriate base protecting groups.
