One of the standard methods used to immobilize DNA on gold surfaces involves two steps: the attachment of a thiol linker group (usually in the form of alkanethiol moiety) to the DNA strand, and the chemical reaction between the …
WebCytosine (C) is methylated at 5′ carbon of the pyrimidine ring by DNA methyltransferases (DNMT-1, DNMT-3A, DNMT-3B), the writer, to generate 5-methylcytosine (5-mC), which is recognized by methyl-CpG binding protein 2 (MeCP2), the reader. Perrine Juillion WebJan 1, 2005 · The less hard the stacking molecule, the larger the charge transfer to the stacked one and the larger its ability for hydrogen bonding. In model complexes of cytosine stacked with substituted benzenes, the hydrogen bonding ability is found to be directly related to the electrostatic part of the interaction between the rings.
