Restriction enzymes typically recognize and cut at specific sequences called restriction sites. The restriction site for the common restriction enzyme EcoRI is GAATTC. The sequence TAGCTA contains the EcoRI restriction site in the reverse complement strand (CTAGAT), indicating it is the most likely DNA sequence to be recognized by the EcoRI restriction enzyme.
