Which of the Following Statements About DNA Methylation in Eukaryotes

Question

Which of the following statements about DNA methylation in eukaryotes is FALSE?
A)Appropriate inheritance of DNA methylation patterns involves maintenance methyltransferase.
B)DNA methylation involves a covalent modification of cytosine bases.
C)Methylation of DNA attracts proteins that block gene expression.
D)Immediately after DNA replication, each daughter helix contains one methylated DNA strand, which corresponds to the newly synthesized strand.

Accepted Answer

Immediately after DNA replication, both daughter helices contain one newly synthesized and one parental strand. Therefore, both daughter helices would have either a methylated or unmethylated strand, depending on the methylation status of the parental strand.
