When DNA is replicated,it is necessary for the two strands to "unzip" temporarily.Choose which bonding type is most appropriate for holding the strands together in this way.
A) non-polar covalent bonding
B) hydrogen bonding
C) ionic bonding
D) polar covalent bonding

Question

Hydrogen bonding is the most appropriate bonding type for holding the two strands of DNA together because it is strong enough to keep the strands held together, but weak enough to be easily broken for replication and transcription. Non-polar covalent bonding and polar covalent bonding are much stronger and would not allow for easy strand separation, while ionic bonding is not strong enough to hold the strands together in the required manner.
