Genomic imprinting is an epigenetic phenomenon which results in the monoallelic expression of a gene depending on the parental origin. Genomic imprints may be covalent (DNA methylation) or noncovalent (DNA-protein and DNA-RNA interactions, genomic localization in nuclear space) and the process of imprinting encompasses the specialized nuclear enzymatic machinery which maintains parental epigenetic marks throughout the life.
