The Correct Answer and Explanation is:
The correct answer is: G1, S, G2, mitosis, cytokinesis
Explanation
The cell cycle is the series of events that a cell goes through as it grows and divides. It consists of several distinct phases that ensure the accurate replication and distribution of the cell’s DNA and organelles to the daughter cells.
The correct order of the cell cycle phases is as follows:
G1 phase – This is the first gap phase after a cell is formed. During G1, the cell grows in size, produces RNA, synthesizes proteins, and prepares for DNA replication. It is a period of intense cellular activity but no DNA synthesis occurs yet.
S phase – In this synthesis phase, DNA replication occurs. Each chromosome is duplicated so that the cell will have two complete sets of DNA. The cell continues to grow and maintain normal functions while ensuring that the genetic material is accurately copied.
G2 phase – This is the second gap phase. The cell continues to grow and produce proteins, particularly those required for mitosis. It also checks for any DNA damage that may have occurred during replication and ensures that all cellular components are ready for division.
Mitosis – Mitosis is the process by which the duplicated chromosomes are separated into two nuclei. This phase is further divided into stages: prophase, metaphase, anaphase, and telophase. Mitosis ensures that each daughter cell receives an identical set of chromosomes.
Cytokinesis – This is the final step in the cell cycle, where the cytoplasm of the parent cell is divided to form two daughter cells. Cytokinesis typically overlaps with the end of mitosis, particularly telophase, but it is considered a separate event that completes the cell cycle.
In summary, the correct and sequential order is G1, S, G2, mitosis, cytokinesis, and each phase plays a crucial role in cell growth and division.
