A nucleotide can be misplaced in a DNA strand during replication. How are misplacements in DNA nucleotide strands corrected so that the final error rate is low?
by supercoing to inactivate the gene region in which a misplaced nucleotide has occurred
by the chemical action of special enzymes that can detect and replace misplaced nucleotides
by lysosomes that move along the strands removing any strands of nucleotides containing misplaced nucleotides
by the complementary DNA strand removing the misplaced nucleotides and connecting the open ends of the strand together
