What happens during DNA replication in the S phase of a eukaryote's cell cycle?

How does DNA replication contribute to cell division preparation?

Answer:

During the S phase of a eukaryote's cell cycle, DNA replicates to prepare for cell division.

During the S phase of a eukaryote's cell cycle, DNA replication is a crucial process that occurs to ensure the accurate replication of genetic material. This phase is essential for cell division preparation as it provides each daughter cell with a complete set of DNA.

DNA replication involves the unwinding of the DNA double helix, forming two replication forks where the DNA strands are separated. Enzymes like DNA polymerase then work to synthesize new DNA strands complementary to the template strands. This process results in two identical DNA molecules, ensuring that each daughter cell receives a complete copy of the genetic material.

By undergoing DNA replication during the S phase, the cell ensures that it is ready for cell division and that each daughter cell has the necessary genetic information for its functions and characteristics.
