DNA has the recipe for the enzyme. DNA opens up, and makes a copy of that recipe, which we call RNA. The RNA that is a direct copy of a certain region in the DNA is called mRNA (messengerRNA). The mRNA binds to a ribosome to form amino acids. The amino acids are brought to the ribosome by tRNA. Loads of tRNA will try to bind to the ribosome, but only those who have a complementary base-sequence to the mRNA can bind. There is one amino acid per three bases. Different tRNA will bind to the ribosome until there is no bases left on the mRNA to bind with. For every tRNA that binds, an amino acid will be made, and the amino acids will bond together as we go along the mRNA. Proteins consists of amino acidsm and the amount and sequence of those amino acids determine which protein/enzyme will be formed.
Hope this was any help.
