Final answer:
Interphase is a phase in the cell cycle where the cell prepares for division and includes the G1, S, and G2 phases. Its length varies, dependent on cell type. The process allows for normal cellular functions, duplication of DNA, and preparation for mitosis.
Step-by-step explanation:
The eukaryotic cell cycle comprises two main components: interphase and the mitotic phase. Interphase is significantly longer than the mitotic phase and is the period during which the cell conducts its regular functions alongside preparing for division. The duration of interphase can vary greatly depending on the type of cell and organism.
Three Stages of Interphase
- Interphase consists of three stages:
G1 Phase (First Gap): The cell grows, increases its supply of proteins, and prepares adequate energy reserves for the upcoming replication.
- S Phase (Synthesis of DNA): The cell replicates its DNA, ensuring each new cell will have a complete set of chromosomes.
- G2 Phase (Second Gap): Further growth occurs, and proteins necessary for cell division are synthesized.
The purpose of interphase is to equip the cell for the successful allocation of identical genetic material to each daughter cell through cell division.
