Question

question 9 of 10 which two statements describe why dna replication is extremely accurate? a. random base pairing of nucleotides means that there are many possible correct base sequences. b. dna polymerase removes and replaces incorrect nucleotides that are added to the growing strand. c. elongation usually stops temporarily if an incorrect nucleotide is added to the growing strand. d. enzymes edit the base sequence in the template strand if it doesnt match the new strand.

Explanation:

DNA polymerase has proof - reading ability (B). Also, replication pauses when an incorrect nucleotide is added (C), which helps maintain accuracy. A is incorrect as base - pairing is not random. D is incorrect as enzymes correct new strands relative to the template, not the template itself.

Answer:

B. DNA polymerase removes and replaces incorrect nucleotides that are added to the growing strand.
C. Elongation usually stops temporarily if an incorrect nucleotide is added to the growing strand.
