A waiver is a formal statement giving up a right. If you go on a school trip, your mom might sign a waiver saying that the school is not responsible if you get hurt on the trip. When you sign a waiver, youâre voluntarily giving up a privilege or legal right. A waiver is often required before you participate in something dangerous.

Molecular cloning is the laboratory process used to create recombinant DNA. It is one of two widely used methods, along with polymerase chain reaction (PCR) used to direct the replication of any specific DNA sequence chosen by the experimentalist. There are two fundamental differences between the methods.
