Witryna14 maj 2024 · The process of imprinting starts in the gametes where the allele destined to be inactive in the new embryo (either the father's or the mother's as the case may be) is "marked". The mark appears to be methylation of the DNA in the promoter (s) of the gene. Methyl groups are added to cytosines (Cs) in the DNA. WitrynaGenomic imprinting, the differential expression of an autosomal gene that is dependent on its parent of origin, has independently evolved in flowering plants and mammals. In both of these organism classes, imprinting occurs in embryo-nourishing tissues-the placenta and the endosperm, respectively.
