Question

AS Part A Which of the following events occurs during DNA replication? All methylation of the DNA is lost at the first round of replication Methylated DNA is copied in the cytoplasm, and unmethylated DNA is copied in the nucleus Methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where ane strand is already methylated and thus comectly methylate daughter strands after replication DNA polymerase is blocked by methyl groups. and methylated regions of the genome are therefore ieft uncopied Submit Request Answer Next Provide Feedback assignmentProblemiD 136572714 MacBook Air 44 0 7 5

Answer 1

Q1) Answer d. Methylation of the DNA is maintained because methylation enzyme act at DNA site where one strand is already methylated and thus correctly methylate the daughter strand after replication.

Q2) Answer d. miRNAs function in controlling gene expression by binding to mRNAs and degrading them or blocking their transition.
