Questions and Answers
What is interphase?
What is interphase?
The cell grows and replicates its DNA and centrioles.
What is prophase?
What is prophase?
The chromatin condenses into chromosomes. The centrioles separate and a spindle begins to form. The nuclear envelope breaks down.
What is metaphase?
What is metaphase?
The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere.

Study Notes
Cell Cycle and Mitosis Overview
- Interphase: Stage where the cell grows, replicates DNA and centrioles; longest phase of the cell cycle.
- Prophase: Chromatin condenses into distinct chromosomes; centrioles separate and form spindles; breakdown of nuclear envelope occurs.
- Metaphase: Chromosomes align at the cell's equator; each chromosome is connected to spindle fibers at its centromere.
- Anaphase: Sister chromatids are separated into individual chromosomes and moved toward opposite poles of the cell.
- Telophase: Chromosomes reach opposite ends; they decondense and two nuclear envelopes reform around each set of chromosomes.
Mitosis Stages Visual Characteristics
- Interphase Appearance: Cell contains chromatin; no visible chromosomes; active cell function and preparation for division.
- Prophase Appearance: Chromosomes are visible as distinct entities; spindles forming; nuclear envelope is disintegrating.
- Metaphase Appearance: Chromosomes lined up neatly at the cell's center, held by spindle fibers; clear organization for separation.
- Anaphase Appearance: Individual chromosomes moving apart; clear separation of sister chromatids toward opposite ends.
- Telophase Appearance: Chromosomes at poles; nuclear envelope begins reforming around each group, leading to the final stages of cell division.
Key Mitosis Questions
- Chromatin to Chromosomes: Occurs during prophase; vital for the orderly separation of genetic material.
- Chromosomes Align: Happens in metaphase; ensures proper distribution of genetic material.
- Longest Cell Cycle Phase: Interphase; encompasses growth and preparation for mitosis.
- Nuclear Envelope Breakdown: Takes place in prophase, facilitating access to the chromosomes for spindle attachment.
- Cytokinesis Description: The process in which the cell divides into two daughter cells, following mitosis.
- Daughter Chromosomes Arrangement: In telophase, chromosomes arrive at cell poles, ready for the formation of two nuclei.
- Sister Chromatids Separation: This occurs during anaphase, crucial for ensuring each daughter cell receives the correct number of chromosomes.
