Mitosis Drawing Draw, color, and label:

– The life cycle of a cell including• Interphase, Prophase, Metaphase, Anaphase,

Telophase, and Cytokinesis. – Make sure to label

• Nucleus, Nuclear Membrane, DNA/Chromosomes, Parent Cells, Daughter Cells.

– Show what is happening to the DNA/Chromosomes at each step of the process.

A Cell Life Cycle

A Cell’s life… Consists of 3

main parts 1. Interphase (I) – cell is

hanging out. 2. Mitosis – If a cell decides

to divide it undergoes Mitosis (PMAT)

3. Cytokinesis (C) – Two daughter cells created

Interphase Phase 1-

Interphase– Cell resting– DNA is in little

single threads. – DNA is doubled

and the cell gets bigger.

Mitosis Phase 2-

Prophase– Mitosis begins– Chromosomes are

in their “x” like shape.

– Centrioles move to poles

– Spindle fibers connect centrioles

DNA change from phase 1 to 2

Interphase DNA is Chromatin (bunch of squiggles with no clear shape)

Prophase DNA is organized into sister chromatids which make a chromosome.

Centriole Change from interphase to Prophase Interphase Prophase – Centrioles

start to move to poles and spindle fibers start to connect them.

Nucleus

Mitosis Phase 3-

Metaphase– They line up in

middle of cell– Chromosomes

attach to spindle fibers

Mitosis Phase 4-

Anaphase– Sister chromatids

pull apart– One sister of each

pair goes to opposite ends of the cell

Mitosis Phase 5-

Telophase– 2 new nuclei form– Mitosis is

complete– Chromosomes are

undone again (chromatin)

Mitosis Phase 6-

Cytokinesis– Cytoplasm

pinches in to form 2 new identical daughter cells
