http://nathansheffield.com/wordpress/what-is-hemimethylated-dna/ WebA hemi-methylated site is a single CpG that is methylated on one strand, but not on the other. This is not the same thing as allele-specific methylation, which is common in imprinting. In hemi-methylation, we’re talking about 2 strands from the same parent.

Web9 mrt. 2024 · DNA methylation is an essential epigenetic modification that regulates gene transcription, embryonic development, and cell differentiation in both animals … Web1 aug. 2024 · Maintenance DNA methyltransferases methylate hemi-methylated sites upon DNA replication, so that the methylated or unmethylated status is inherited on both of the two newly synthesized DNA molecules. Therefore, DNA methylation serves as a marker on genomic DNA that can persist over cell generations.
