Question

Match the letters on the image below with the corresponding part of the cell cycle.

Answer 1

The stages of the cell cycle and mitosis include interphase (G1, S, G2 phases) followed by mitosis (prophase, prometaphase, metaphase, anaphase, telophase) and conclude with cytokinesis.

Step-by-step explanation:

The question is about the stages of the cell cycle and mitosis, which are key aspects of cell biology. The cell cycle is a series of events that cells go through as they grow and divide. It is composed of two major phases: interphase, which includes the G1, S, and G2 phases, and the mitotic phase, which includes mitosis and cytokinesis. During mitosis, the main events occur in the following order: prophase, where chromosomes condense, prometaphase, where the nuclear envelope breaks down, metaphase, where chromosomes align at the cell equator, anaphase, where sister chromatids separate and move to opposite poles, and telophase, where two new nuclei form in preparation for cell division.

Answer 2

Answer: The cell cycle refers to the series of events that occur in a cell as it grows, replicates its DNA, and divides into two daughter cells. It consists of four main stages:

1. G1 Phase (Gap 1): During this phase, the cell grows in size, produces proteins, and carries out its normal functions. It is a period of active metabolism.

2. S Phase (Synthesis): In this phase, DNA replication takes place. The cell duplicates its genetic material to ensure that each daughter cell receives a complete set of chromosomes.

3. G2 Phase (Gap 2): The cell continues to grow and prepare for cell division. It synthesizes proteins and organelles needed for the upcoming division.

4. M Phase (Mitosis): This phase involves the actual division of the cell into two daughter cells. It consists of several steps, including prophase, metaphase, anaphase, and telophase, which ensure the equal distribution of chromosomes and cytoplasm between the daughter cells.

These stages collectively make up the cell cycle, which is a continuous process that allows cells to grow, repair, and reproduce. Each stage has specific functions and is tightly regulated to ensure proper cell division and genetic stability.
