How do dietary factors interact with DNA methyltransferase to affect an organism's phenotype in an epigenetic manner? Some dietary factors degrade DNA methyltransferase, preventing it from removing methyl groups from sections of DNA, thereby altering gene expression Some dietary factors interact with methyl groups directly preventing DNA methyltransferase from methylating any DNA, changing gene expression in the organism as a result Some dietary factors inhibit DNA methyltransferaseactivity, reducing the methylation of the organism's DNA and changing its gene expression     Some dietary factors bind toDNA methyltransferaseand enable it to methylateDNA, thereby changing geneexpression   Some dietary factors upregulate DNA methyltransferase activity, increasing the overall methylationof the organism's DNA and changing its gene expression
