Fruit Proof Reading
The Saturday Museum | Digital Image
Make a line of fruit using a blueberry, a cherry tomato, a grape and a slice of banana. First add an extra tomato in the sequence. Then eat. Then eat the blueberry.
This kitchen experiment was created by Sarah and Lynne. It helps us to understand how, during DNA replication, polymerases proof read the DNA sequence to see if there is anything they need to correct. If there is too much of something it is called an insertion. If something is missing it is called a deletion.
