What is interphase?
What is interphase?

Flashcards
Interphase
Interphase
The stage of the cell cycle where the cell grows, copies its DNA, and prepares for division.
Prophase
Prophase
The first phase of mitosis, where chromosomes condense, the nuclear membrane breaks down, and spindle fibers form.
Metaphase
Metaphase
The stage of mitosis where chromosomes line up at the center of the cell, attached to spindle fibers.

Study Notes
Cell Division Phases
- Interphase: DNA replication occurs, preparing the cell for division.
- Prophase: Chromosomes condense, the nuclear membrane dissolves, and spindle fibers begin to form.
- Metaphase: Chromosomes align at the cell's equatorial plane and attach to spindle fibers.
- Anaphase: Chromosomes are separated into chromatids that move toward opposite poles of the cell.
- Telophase: New nuclear membranes form around each set of daughter chromosomes; chromatin begins to detangle.
- Cytokinesis: The cytoplasm divides, resulting in two distinct daughter cells.
Key Events in Cell Division
- DNA duplication only occurs during interphase.
- Individual chromosomes are no longer visible during interphase, telophase, and cytokinesis.
- The longest phase of the cell cycle is interphase, while metaphase is the shortest.
Roles and Structures
- Centrioles are responsible for producing spindle fibers and organizing chromosome movements.
- During metaphase, a cell will demonstrate a single line of chromosomes aligned at the center due to spindle fiber attachment.
Overview of Mitosis Stages
- Mitosis consists of four main stages: prophase, metaphase, anaphase, and telophase, each playing a critical role in cell division.
