The initiation of DNA replication<span> occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the </span>DNA<span> double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the </span>DNA<span> strands, thereby pulling apart the two strands.</span>
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body's cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
