Taq Polymerase Drawbacks

Talk:Real-time polymerase Chain Reaction – Wikipedia, The …
The article sas: "breakdown of the probe by the 5' to 3' exonuclease activity of the Taq polymerase breaks the reporter-quencher proximity and thus allows unquenched emission of fluorescence" but when you see the Taq polymerase article it says: "One of Taq's drawbacks is its relatively low … Read Article

Taq Polymerase Drawbacks

Taq polymerase – Wikipedia, The Free Encyclopedia
One of Taq's drawbacks is its relatively low replication fidelity. It lacks a 3' to 5' exonuclease proofreading activity, and has an error rate measured at Use of the thermostable Taq polymerase eliminates the need for having to add new enzyme to the PCR reaction during the thermocycling process. … Read Article
