Recognition Sequence
A Recognition Sequence (pronunciation: /rɛkəɡˈnɪʃən ˈsiːkwəns/) is a specific series of nucleotides in DNA that is identified and cut by a restriction enzyme. These sequences are also known as restriction sites.
Etymology
The term "Recognition Sequence" is derived from the English words "recognition" and "sequence". "Recognition" comes from the Latin word "recognitio", meaning "knowledge of", and "sequence" comes from the Latin word "sequentia", meaning "following".
