DNA polymerase PolA has high fidelity but low processivity, and DNA polymerase PolB has low fidelity and high processivity. In vitro reactions for DNA synthesis using limiting amounts of PolA or PolB were set up to further characterize the enzymes according to the following scheme: Tube 1: PolA + T7 DNA (20 min) + T3 DNA (40 min) Tube 2: PolB + T7 DNA (20 min) + T3 DNA (40 min) Which of the following outcomes do you expect?
