Introduction:
All eukaryotic cells have a cell cycle. The cell cycle consists of two phases: mitosis and interphase. Most of the time, eukaryotic cells are in a condition called interphase.
Explanation:The cell cycle interphase consists of 3 subphases:
1. G1 phase: Period between the end of mitosis and the start of synthesis.
2. S phase: DNA replicates (S for synthesis). Because the chromosomes replicated during the S phase, each chromosome now consists of two identical sister chromatids. DNA replication occurs inside the nucleus of the cell.
3. G2 phase: Between the end of the S phase and the beginning of mitosis. There is a preparation for mitosis: the synthesis of microtubules that will later move the chromosomes to opposite sides of the dividing cell.
According to the above information, we can conclude that the correct answer is:
Answer:DNA replicates in the cell nucleus of the eukaryotic cell, during the synthesis phase of the cell interfase.
