During DNA Replication

question 84

Multiple Choice

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 is copied in the nucleus.
