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 methylates 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.
E)methylated DNA is copied in the cytoplasm, and unmethylated DNA in the nucleus.

Methylation of the DNA is maintained during replication because the methylation enzymes recognize and methylate daughter strands at the same sites as the template strands that were already methylated. This ensures that the new DNA molecules have the same methylation patterns as the original DNA.
