Answer: B) G2
Explanation: G1) first gap phase; the cell grows larger and organelles are copied
S) synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus
G2) second gap phase; the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis
M) mitosis phase; the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter cells.
So DNA replicates in S phase but then it moves to G2
