Which of the following is a requirement for a successful cell cycle?

A successful cell cycle indeed requires several key processes to ensure that the cell divides correctly. One important aspect is that the S phase, where DNA is replicated, must occur before mitosis. This sequencing is critical because mitosis relies on having an accurate and complete copy of the genetic material to distribute to daughter cells.

Additionally, the presence of checkpoints before and after the S phase is essential for the integrity of the cell cycle. These checkpoints serve as quality control mechanisms that can halt the cycle if issues such as DNA damage or incomplete replication are detected, thereby preventing the propagation of errors.

Furthermore, it is important for cells to maintain a balance in the replication of both DNA and cytoplasmic organelles. When a cell divides, not only must the genetic material be duplicated, but the components essential for cell function—like mitochondria, ribosomes, and other organelles—must also be accurately distributed between the two new cells.

The selection that encompasses all these factors confirms that each element plays a vital role in ensuring the accuracy and health of cell division. By meeting these requirements, cells can effectively replicate, thus contributing to growth, repair, and maintenance of tissue.
