G2 Phase
Captions available
The idea
G2, the second gap phase, is when a cell replenishes its energy stores and synthesizes the proteins needed to move and separate chromosomes during mitosis.
In practice
A crew stocking spare tools before a shift mirrors G2's final gathering, readying equipment before mitosis's work begins.
Where people slip
G2 is checkpoint-guarded, not guaranteed — a cell with unfinished DNA replication or damage can be held here.
