Restriction Enzymes

Nicole G, Kate G, Dalonta W, and Naomi B

What are restriction enzymes?

Restriction enzymes are enzymes that help to cut the DNA at a specific enzyme. They perform very specific and precise actions.

What do they do, or how do they function?

A restriction enzyme will only cut the DNA if the sequence matches properly. Otherwise the enzyme wouldn't be able to do its job properly. First the enzyme will bond to the sequence and if it fits it will cut it. The enzyme will cut the sequence so it will be able to reattach with another one.

Why are they useful?

They are useful because they manipulate DNA, and they help with genetic engineering.

Restriction enzymes also help you analyze the individual sequences in DNA.
