Final answer:
During interphase, the nucleus undergoes growth, DNA replication, and prepares for division through three stages: G₁ phase, S phase, and G₂ phase.
Step-by-step explanation:
During interphase, the nucleus undergoes several important processes in preparation for cell division. Interphase is divided into three stages: G₁ phase, S phase, and G₂ phase.
- G₁ Phase: During this stage, the cell is actively accumulating the building blocks of chromosomal DNA, associated proteins, and energy reserves that are needed for DNA replication.
- S Phase: In this phase, DNA replication occurs, resulting in the duplication of the nuclear DNA.
- G₂ Phase: The cell continues to grow and prepare for mitosis by synthesizing more proteins and organelles.
Overall, interphase is a crucial period in the cell cycle where the nucleus undergoes growth, DNA replication, and prepares for division.
During interphase, the nucleus is the site of critical preparatory activities leading to cell division. The interphase consists of three main stages: the G1 phase, S phase, and G2 phase. In the G1 phase (First Gap), the cell focuses on growth and accumulates the necessary components for DNA synthesis, including the building blocks of chromosomal DNA, associated proteins, and energy reserves. The S phase (Synthesis) is where the actual replication of DNA occurs, making a complete copy of the cell's genome. Following DNA synthesis, the cell enters the G2 phase. Here, it continues to grow and produces proteins and organelles in anticipation of cell division. These stages ensure the cell is ready to enter the mitotic phase.
