These are the 'cooks', but they are not shown here. The two spirals of the DNA are slit apart quite easily. To make a protein, part of the the DNA gets split. New bases are matched match up on one side of the split DNA, but these bases are a bit different. Instead of A being matched by T, it is matched by a new base called U.

Bit by bit, a new chain of bases gets made. It is called RNA.

This RNA is going to carry a message. The message is the recipe for a protein. This RNA is called __messenger RNA__, or __mRNA.__

When the messenger RNA is complete, the two DNA strands join up again and the mRNA is ready for the next part.
