Step 3 Nucleus, Nucleoli and Chromatin

Nucleus:
The nucleus is a membrane bound organelle that holds the cells DNA.
Nucleolus
The nucleolus is the site of ribosomal RNA synthesis.
Chromatin
Chromatin consists of DNA and its associated proteins.

Cutting

• Cut out a large circle of felt, this will be the largest component of the cell; the nucleus.
• Cut out a circle of felt in a different colour with roughly 1/4 the diameter of the nucleus, this will be the nucleolus.
• Cut out several little 'X' and 'V' shaped felt pieces of a third colour. These are the chromosomes(chromatin).

Sewing

• First sew the nucleoli to the nucleus.
• Then sew the chromosomes onto the nucleus.
• Then sew the whole thing to the the cell (that blue piece of fabric from step 2).
