content: This silver metal canister once contained Eco RI, an enzyme commonly used in molecular biology. Eco RI belongs to a class of enzymes known as restriction enzymes, which are useful for their ability to cleave DNA only at locations containing specific sequences of nucleotides, the small chemical units that make up the longer DNA molecule. Eco RI recognizes the sequence GAATTC and will cut between the G and first A.
