1 pt 1 Question 1 Why must one strand of DNA be replicated in fragments? DNA polymerase can only add 20 nucleotides in a strand and then must start over ODNA polymerase can only add nucleotides to the 3 hydroxyl of a growing strand O it would be too crowded for two DNA polymerases to be going in the same direction all of the above Question 2 1 pt the DNA would spin and possibly break while being opened in...
