DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.
Erfahre, was DNA Methylierung ist, wie sie funktioniert und welche Rolle sie bei der Genregulation spielt. Lerne die Unterschiede zwischen Eukaryoten und Prokaryoten, sowie zwischen Methylierung und Mutation kennen.
11. Juli 2012 · In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. DNA methylation...

Bei der DNA-Methylierung handelt es sich um eine chemische Abänderung an Grundbausteinen der Erbsubstanz einer Zelle. [1] . Diese Abänderung (Modifikation) wird durch die Übertragung von Methylgruppen durch Enzyme ( DNA-Methyltransferasen) auf Nukleobasen an bestimmten Stellen der DNA bewirkt.
In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. DNA methylation regulates gene expression by recruiting proteins involved in gene repression or by inhibiting the binding of tra ….
