Problem: How does the structure of DNA help prevent errors from occurring during DNA replication?
A. RNA primers are added to specific sequences on the template strands so that replication always starts at the same place.
B. The strength of the sugar-phosphate backbones prevents nucleotides from becoming separated or getting out of sequence.
C. Weak hydrogen bonds make it easy for DNA ligase to remove and replace sequences that contain mistakes.
D. Due to the complementary nature of base pairing, elongation is paused when DNA polymerase adds the wrong nucleotide.
