WebTOPO® Cloning. Toposiomerase based cloning, often called TOPO® cloning or TA cloning, is a method that relies on the hybridization of the complementary base pairs adenine (A) and thymine (T). TOPO® cloning utilizes the Taq polymerase which naturally leaves a single adenosine (A) overhang on the 3' end of PCR products. WebCloning a gene usually involves copying the DNA sequence of that gene into a smaller, more easily manipulated piece of DNA, such as a plasmid. This process makes it easier to study the function of the individual gene …
