GABA A receptors are Cl– channels, and the resulting Cl– influx hyperpolarizes the A cells to inhibit glucagon secretion

The core on the leading strand is processive because its clamp keeps it on the DNA.

The clamp associated with the core on the lagging strand dissociates at the end of each Okazaki fragment and reassembles for the next fragment.

The length of the priming RNA is limited to eight to 14 bases. Apparently, DNA polymerase III is responsible for displacing the primase.
