In this lab our group used pipe cleaners and string to model mitosis

 

Interphase

The small circle represents the nucleus and the bigger circle represents the cell membrane.

There are chromatins inside the nucleus.

During the interphase, all of the DNA is copied. We added the other half of the pipe clearners.

 

Mitosis

<Prophase>

Replicated DNA molecules join together to form sister chromatids. Two same colour and size pipe cleaners are tied together.

We added small strings to the cell, 4 at each end, to represent the spindle fibres.

We attached the strings from either end of the cell to one of the sister chromosomes.

The nucleus is removed.

<Metaphase>

The chromosomes line up in the middle of the cell.

<Anaphase>

We untied the sister chromatids and moved the 2 halves of each chromosome away from each other to opposite sides of the cell.

<Telophase>

The spindle fibres disappears and 2 nuclear membranes form.

 

Cytokinesis

Cell divides into two.
