Mr Barnes came to visit yesterday and showed us how to extract DNA from strawberries!
First we squashed the strawberries.
We mixed the squashed strawberry with water, salt and dishwashing liquid.
We sloshed it around.
Mr Barnes poured the strawberry juice into a filter to get all of the seeds out.
Only clear liquid was left.
He tipped in some purple methylated spirits.
It floated on top.
We could pull the DNA out on a stick.
DNA is the instructions of how to make a living thing.
