Light rare earth elements stabilize G-quadruplex structure in variants of human telomeric sequences.

Recently, light rare earth elements (LREEs) are gaining importance in modern-day technologies. Thus, the entry of LREEs into biochemical pathways cannot be ignored, which might affect the conformation of biomacromolecules. Herein, for the first time, we discover the G-quadruplex formation in the human telomeric variants in presence of micromolar concentrations of LREEs.
