Restriction enzymes, such as Eco RI, are used in a wide variety of molecular genetics techniques including cloning , DNA screening and deleting sections of DNA in vitro . Restriction enzymes, like Eco RI, that generate sticky ends of DNA are often used to cut DNA prior to ligation , as the sticky ends make the ligation reaction more efficient. Eco RI can exhibit non-site-specific cutting, known as star activity , depending on the conditions present in the reaction. Conditions that can induce star activity when using Eco RI include low salt concentration, high glycerol concentration, excessive amounts of enzyme present in the reaction, high pH and contamination with certain organic solvents.
