Verified
Which of the following events occurs during the G₂ phase of the cell cycle?
A) Completion of cell growth and production of enzymes
B) DNA replication
C) Synthesis of substances and materials that will be needed in the S phase
D) Separation of sister chromatids, and migration toward opposite sides of the dividing cell
E) Dispersal of the nucleolus and nuclear envelope
DNA Replication
The process by which a cell duplicates its DNA, making two identical copies, before cell division.
Sister Chromatids
Identically replicated forms of a chromosome connected by a centromere, formed during cell division.
Enzymes Production
The process by which living organisms synthesize enzymes, proteins that catalyze biochemical reactions.

Final Answer :
A
Explanation :
During the G₂ phase of the cell cycle, the cell completes its growth and produces enzymes and other proteins necessary for mitosis. DNA replication occurs in the S phase, not G₂. The synthesis of materials needed for the S phase happens in the G₁ phase. Separation of sister chromatids and their migration, as well as the dispersal of the nucleolus and nuclear envelope, occur during mitosis, not the G₂ phase.
