During cell division, both DNA replication and cell growth take place.

DNA Replication:
During cell division, the process of DNA replication occurs. DNA replication is the process by which a cell makes an identical copy of its DNA. This is a crucial step in cell division as it ensures that each daughter cell receives a complete set of genetic information. DNA replication begins with the unwinding of the DNA double helix and the separation of the two strands. Enzymes called DNA polymerases then attach to each separated strand and add complementary nucleotides, creating two new identical strands. This results in two complete copies of the DNA molecule.

Cell Growth:
In addition to DNA replication, cell growth also takes place during cell division. Before a cell can divide, it needs to increase its size and accumulate enough cellular components to ensure that each daughter cell receives an adequate amount of organelles and cytoplasm. This growth phase is known as the interphase, which occurs before the actual division process.

During interphase, the cell undergoes various metabolic activities, such as protein synthesis, organelle replication, and an increase in cytoplasmic volume. This ensures that when the cell divides, each daughter cell will have enough resources to function properly. Cell growth is a critical aspect of cell division as it ensures the viability and functionality of the resulting daughter cells.

Conclusion:
In summary, during cell division, both DNA replication and cell growth take place. DNA replication ensures that each daughter cell receives a complete set of genetic information, while cell growth ensures that each daughter cell has enough resources to function properly. These processes are essential for the successful division and proliferation of cells.
