TLDR

Temperature dependent behavior of chemical shifts and the difference in chemical shifts between the C1'-H and C2'-H resonances clearly indicated whether the nucleoside exists in a syn glycosyl conformation or as a flexible syn-anti mixture (the monomethylamino and amino derivatives).

TL;DR: The case of quadruplexes formed by monomeric guanosine derivatives, where there is no strand connecting the adjacent quartets and the definition parallel/antiparallel strands cannot apply, will be discussed.

Science

TL;DR: A study of 20 base triplets reveals that the triple helix can be extended from homopurine to mixed sequences, and Guanine contained within a pyrimidine oligonucleotide specifically recognizes thymine.

TL;DR: In this chapter the CD spectral features characteristic of different folding topologies of G4-DNA are analyzed in terms of the sequence of the syn or anti glycosidic bond angle (GBA) within a quadruplex stem.

TL;DR: The model presented in this study should be useful as DNA-sequence analysis becomes more commonly applied to the study of mutagenesis, and as DNA structure at and surrounding ionized base pairs may be altered.

Organic and Biomolecular Chemistry

TL;DR: The conformational features found in the three quadruplexes might, in principle, amplify the range of applicability of synthetic oligonucleotides as aptamers or catalysts, by providing novel structural motifs with different molecular recognition capabilities from those of native DNA sequences.
