Which of the Following Events Occurs During DNA Replication

Which of the following events occurs during DNA replication?

A) All methylation of the DNA is lost at the first round of replication.
B) DNA polymerase is blocked by methyl groups,and methylated regions of the genome are therefore left uncopied.
C) Methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylate daughter strands after replication.
D) Methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template.
