Why do you think a cell needs to make more DNA at the S Phase of the cell cycle?

During the S Phase of the cell cycle, a cell replicates its DNA to ensure that each daughter cell receives an identical set of genetic information after cell division. This duplication is crucial for maintaining genetic continuity and supporting the proper function of the new cells. Without accurate DNA replication, cells could end up with incomplete or damaged genetic material, leading to malfunctions or diseases such as cancer. Therefore, making more DNA is essential for growth, development, and tissue repair.
