In a single covalent bond
Webdescribes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair of electrons shared between the two bonded atoms. We say that orbitals on two different atoms overlap when a portion of one orbital and a portion of a second orbital occupy the same region of space.

WebJan 1, 2024 · The aptamer, a short, single-stranded DNA molecule, is functionalized with a cleavable, label-transferring electrophile. Once the aptamer associates with its protein target, the tethered electrophile is brought into proximity with a nucleophilic residue, followed by fast and selective label transfer via covalent bond formation.
