Question

which of the following would cause an error in dna replication? a. dna polymerase pairing c with g b. dna polymerase checking the dna c. the original dna strands never being separated d. dna ligase connecting chunks of dna

Explanation:

DNA replication requires the separation of the original DNA strands so that new complementary strands can be synthesized. If the original strands are never separated, replication cannot occur properly, causing an error. Option A is a correct base - pairing action by DNA polymerase, option B is a proof - reading function that helps prevent errors, and option D is a normal step in DNA replication for joining Okazaki fragments.

Answer:

C. The original DNA strands never being separated
