Chemical reactions are speeded up by enzymes (= proteins, = organic molecules) or more in general: by catalyst

Catalyst
Tyrosine is an enzyme which helps bond with other bass like Cytosine or Guanine to help speed up catalyst reactions in the body. They speed them up by lowering the activation level. These are produced naturally in the body.

Molecules that act as catalysts in biological systems are enzymes. Enzyme catalyze chemical reactions by lowering the activation energy.
The general term is "polymerization reactions." The main types of polymerization reactions are condensation reactions (a small molecule is lost at each step) or addition reactions (no molecule is lost at each step). Each of these is then further subdivided into categories depending on the specific chemistry that's involved.

They are attached to a deoxyribose sugar.
Reactions in the body need a certain amount of energy, called activation energy. Most reactions don't take place because this activation energy is too high. The enzyme bonds to the molecule which diminguishes the activation energy, so the reaction can take place. These enzymes de-bond from the new formed molecule afterwards.
