In genetic engineering techniques, two DNA molecules or one DNA molecule are cleaved at both ends to be paired and then covalently linked by a ligase. Synthetic hexamer linkers (incisions containing a specific enzyme) are now commonly used, or multiple hexamer linkers can be joined together to form a polylinker.
