JMU BIO 140 Exam 2| 335 Questions with 100% Correct Answers What occurs to the two strands of the parental duplex during replication? Correct Answer: they separate Is replication conservative, semi-conservative, or dispersive? Correct Answer: semi-conservative What does it mean to be conservative? Correct Answer: the original DNA is kept and an exact replica is made What does it mean for DNA is be dispersive? Correct Answer: parts of the old and new DNA are chopped together ...
