Atrial systole 

ventricle is relaxed, & because the AV valve is open, the ventricle is filling with blood from the atrium, even prior to atrial systole.

Lytic growth proceeds when PL and PR remain switched on while PRM is kept off. Lysogenic growth, in contrast, is a consequence of PL and PR being switched off and PRM switched on.

When DNA is extensively damaged (such as by UV light. RecA protein binds to this damaged, single-stranded DNA, activating the protein's coprotease activity. While bound to DNA, the RecA protein facilitates cleavage and inactivation of the Lex and Lambda repressor.
