I. True or False, 25 points (5 each), Read the following statements and indicate whether the statement is true or false. For extra credit (5 points each) explain how the false statements are not true. 3. DNA polymerase I performs proofreading by requiring a higher concentration of the next dNTP following a mismatch, allowing time for unwinding of the nascent duplex and 3 5' exonuclease digestion. 4. The DNA duplex of the genome is flexible enough to allow many values...
