Polypeptide chains undergo some modifications before they become fully functional. Some of these modifications include: proteolytic cleavage, lipidation and glycosylation. Proteolytic cleavage refers to the removal of some amino acids from a polypeptide chain by proteases in order for the protein to become active. An example of a substance that is modified through this process is insulin.

The process of confirmation include the following sequence;
1. President nominates
2. Senate committee examines
3. Senate debates
4. Floor vote is taken.
The confirmation process begins when the President selects a nominee for a vacant judgeship. The president then refers the nominee to the Senate Judiciary Committee. The Judiciary Committee holds a hearing on the nominee and then the judiciary votes on whether to report the nominee to the full Senate. The full Senate has the opportunity to debate the nomination and if any senator objects to unanimous consent, then a cloture motion must be filed in order to end debate and move to a vote. Once the senate holds a confirmation vote, with a majority voting to confirm, the nominee becomes a federal judge.
