Gap
Definition:
(n.) An opening in anything made by breaking or parting; as, a gap in a fence; an opening for a passage or entrance; an opening which implies a breach or defect; a vacant space or time; a hiatus; a mountain pass.
(v. t.) To notch, as a sword or knife.
(v. t.) To make an opening in; to breach.
Example Sentences:

(2) We conclude that removal of dimers and repair of gaps were similar in all cases.
(3) Hence the major role of the 14-A arm of carboxybiotin is not to permit a large carboxyl migration but, rather to permit carboxybiotin to traverse the gap which occurs at the interface of three subunits and to insinuate itself between the CoA and keto acid sites.
(4) The junctional currents were already constant 1 ms after step changes in the junctional voltage; this was three orders of magnitude faster than the other known examples of voltage-controlled gap junctions between embryonic cells.

(9) To a large extent, the failure has been a consequence of a cold war-style deadlock – Russia and Iran on one side, and the west and most of the Arab world on the other – over the fate of Bashar al-Assad , a negotiating gap kept open by force in the shape of massive Russian and Iranian military support to keep the Syrian regime in place.
(10) These activities define both the polarity of the anterior-posterior (AP) axis and the spatial domains of expression of the zygotic gap genes, which in turn control the subsequent steps in segmentation.
