But fear not. How it is Done??? RNA triggers for DNA methylation can come from different sources, including invasive viral, transgene or transposon sequences, and in some cases are derived from single- stranded RNA precursors by RNA-dependent RNA polymerases. The mechanism by which RNA signals are translated into DNA methylation imprints are not clear but certain models have been proposed. That is, a gene which would be expressed (“turned on”) under normal circumstances is switched off by machinery in the cell. Get ideas for your own presentations. , 2018).
