Verma, P. S., & Agrawal, V. K. (2006). 3'-TTCGAA-5', breaks between AA. Name the types of nitrogenous bases present in the RNA. Most enzymes are named by combining the name of the substrate with the -ase suffix (e.g., protease, urease). Enzymes with the same recognition sequence do not necessarily cut at the same position of restriction site. For example, the enzyme Hin d III was isolated from The sites of cleavage occur in or near very specific palindromic sequences of bases called recognition sites, which are generally 4 to 8 base pairs long. Knowledge of these unique areas is the basis for DNA fingerprinting. Restriction Enzyme names come from the bacteria where the enzymes are found/ isolated from.
