G2 of Interphase

Definition

G2 of Interphase is the final sub-phase of Interphase where the cell undergoes rapid growth and prepares for mitosis. It involves the synthesis of proteins and organelles needed for cell division.

5 Must Know Facts For Your Next Test

1. G2 phase follows the S phase, where DNA replication occurs.
2. During G2, the cell checks for DNA damage and ensures all proteins necessary for mitosis are present.
3. The G2/M checkpoint is critical for preventing cells with damaged DNA from entering mitosis.
4. Cyclin-dependent kinases (CDKs) and cyclins are crucial regulators in this phase.
5. Completion of G2 results in entry into prophase of mitosis.
