question 11

Multiple Choice

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.
• E) Methylated DNA is copied in the cytoplasm, and unmethylated DNA is copied in the nucleus.
