Chingoo:
I'm not entirely sure how DNA is extracted and how it could be illustrated in a model, but you can illustrate a DNA molecule, mitosis/meoisis taking place (though it would require a lot of effort if you want it to be a working model) and perhaps fertilization in animals/plants depending on the manpower and tools you have available.

Amelia:
DNA extraction is an experimental process. We did it with 'Onion's' in A levels... but here's a link that shows how to extract DNA of Pea's.

kunal:
