Essential Question: How can I
identify and analyze phases of the
cell cycle?
STANDARD: 5A THE STUDENT WILL BE ABLE TO DESCRIBE THE
STAGES OF THE CELL CYCLE, INCLUDING DEOXYRIBONUCLEIC ACID
(DNA) REPLICATION AND MITOSIS, AND THE IMPORTANCE OF THE
CELL CYCLE TO THE GROWTH OF ORGANISMS

Tip
Interphase: Nucleus is still visible
Most cells are in this phase (G1, S,
G2)
Interphase: Nucleus is still visible
Most cells are in this phase (G1, S,
G2)
Prophase: Nucleus disappears,
Individual chromosomes condense
and are visible.
Interphase: Nucleus is still visible
Most cells are in this phase (G1, S,
G2)
Prophase: Nucleus disappears,
Individual chromosomes condense
and are visible.
Metaphase: Chromosomes move
to center of the cell and line up.
Interphase: Nucleus is still visible

Prophase: Nucleus disappears,
Individual chromosomes condense
and are visible.
Metaphase: Chromosomes move
to center of the cell and line up.
Anaphase: Chromosomes move
apart to opposite sides of the cell.

Metaphase: Chromosomes move
to center of the cell and line up.
Anaphase: Chromosomes move
apart to opposite sides of the cell.
Telophase: Chromosomes regroup
and begin to form two NEW nuclei.
The cell cycle is an on-going process.
The pictures below are “snapshots” of cells at
various stages of mitosis.
The cells will continue through the process and
repeat until they die.
Your turn….
Cell Cycle Comic
Create a 6-strip comic page describing the process of Mitosis.
– Be creative in the representation of your setting and characters
– Include thought bubbles and character names (Chromosome, Nucleus,
Cell, DNA, etc…)
– Must include the following words (underline/highlight/use different color)
Replication
Chromosome Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Interphase
