DNA replication is ___________, which allows each of the two strands to serve as a _______ for the new strands.



b. semiconservative, template Correct Answer: DNA replication is semiconservative, meaning that each new duplex has one original (parent) strand and one new strand. Because the two parent strands are separated during replication and the base pairing is predictable, each parent strand can serve as a template for the new strand synthesis.
