WebApr 10, 2024 · Background Canonical telomeres (telomerase-synthetised) are readily forming G-quadruplexes (G4) on the G-rich strand. However, there are examples of non-canonical telomeres among eukaryotes where telomeric tandem repeats are invaded by specific retrotransposons. Drosophila melanogaster represents an extreme example with … WebScience Chemistry Account for the following: (i) Nitrogen does not form pentahalides.
