      I don’t know why. But it is very convenient for TA cloning. And it seems to be a unique chareacteristic of the Taq polymerase, others like Pfu do not do that. I have never seen any explanation for the why.

      I really doubt it actually has a role, honestly. I think it’s much more probable that it’s simply a result of drift in evolution… But this is just my opinion
