When dark‐treated chloroplasts are exposed to light;

The flow of protons from the stroma into the thylakoid lumen is coupled to the release of Mg2+ from the intrathylakoid space to the stroma.

In mammalian systems (where the DNA polymerase does not have a 5'- 3' exonuclease

activity), Okazaki fragments are connected by a two-step process. Synthesis of an Okazaki fragment displaces the RNA primer of the preceding fragment in the form of a "flap’’.

The base of the flap is cleaved by the enzyme FEN1 (flap endonuclease 1 ) .
