Question

How is accuracy maintained during DNA replication?

A. After the new strand is made, RNA primers are removed and
replaced with DNA.
OB. DNA polymerase removes and replaces an incorrect nucleotide
before moving on to the next one.
C. If an error is made, the new strand is removed from the template
strand and replication starts over.
OD. The lagging strand serves as a backup copy for the leading strand
in case any errors occur.
