The T-DNA flanking sequences (FST) have been …Key points: Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends. DNA ligase is a DNA-joining enzyme.22.
