Which phase of the cell cycle follows the DNA synthesis phase?

The correct answer is G2, which is the phase of the cell cycle that follows the DNA synthesis phase, known as the S phase. During the S phase, the cell replicates its DNA, resulting in two complete sets of chromosomes. Following this critical phase, the cell enters G2, where it prepares for mitosis.

In the G2 phase, the cell continues to grow and produces the proteins that are necessary for chromosomal manipulation and cell division. This phase involves the final preparations for mitosis, including the synthesis of proteins and organelles necessary for the division process. The cell also undergoes a series of checks to ensure that the DNA is correctly replicated and that any damage to the DNA is repaired before proceeding to the next phase.

The other phases mentioned are distinct from G2. G1, or the first gap phase, occurs before DNA synthesis, and mitosis (M phase) is the stage where the actual division of the cell takes place after G2. The S phase itself is where DNA synthesis occurs, which is why cells transition into G2 immediately after this phase is completed. Thus, G2 is indeed the correct answer as it directly follows the DNA synthesis phase in the cell cycle.
