Question 6 1 pts You created a mutant form of DNA polymerase in which the 3'to 5'exonuclease (proofreading] function has been destroyed, although its polymerase activity is still fine. Which of the following properties do you expect the mutant polymerase to have? O It will polymerize in both the 5-to-3' direction and the 3-to-5' direction. O It will likely make a new strand of DNA (same length) slower than a normal polymerase. It will be more likely to generate thymidine...
