Restriction enzyme (endonuclease) based molecular cloning is the "classic" cloning method, and for many reasons, remains one of the most popular today. Due to the sequence overlap, the single strand from A will anneal with the single strand from B. Now that your DNA fragment has been cloned into a donor plasmid, it can be rapidly shuttled into any compatible Gateway Destination vector, which contain attR sites via LR clonase enzymes. TOPO cloning utilizes the Taq polymerase which naturally leaves a single adenosine (A) overhang on the 3' end of PCR products. The DCN CDS has been inserted before the GFP CDS and is flanked by both primers. Gibson Assembly is a popular way to insert fragments into a plasmid without using restriction enzymes. The article is a special kind of scientific communication. Except for golden GATEway cloning, all other cloning methods listed above are exonuclease (either 5' - 3' or 3' - 5') based and depend on a short stretch of homology at their ends.
