Cell Membrane (White yarn on outside), Nucleus (White yarn inside), Chromatin (Pipe Cleaners), Spindle fibres (pink yarn), DNA (beads on ends of pipe cleaners).
Interphase:
At the beginning of Interphase DNA is being copied.
Near the end the chromosomes are doubled. Spindle fibres are not visible at any part of interphase.
Prophase:
Replicated DNA molecules join together to form sister chromatids.
Metaphase:
Chromosomes line up in middle of cell.
Anaphase:
Sister chromatids separate into two halves. They move to opposite sides of the cell.
Telophase:
Spindle fibres disappear two new nuclear membranes form.
Cytokinesis:
Cell divides into two.
