Question

question 6 of 10
which of the following would cause an error in dna replication?
a. dna polymerase checking the dna
b. dna polymerase pairing c with g
c. dna ligase connecting chunks of dna
d. the original dna strands never being separated

Explanation:

DNA replication starts with the separation of the original DNA strands. If this doesn't happen, replication can't occur. DNA polymerase checking (A) helps correct errors. DNA polymerase pairing C with G (B) is normal base - pairing. DNA ligase connecting chunks (C) is part of the normal replication process (in lagging strand synthesis). But without strand separation (D), there's no template for new strand synthesis, causing an error.

Answer:

D. The original DNA strands never being separated
