Genomic imprinting is generally due to the addition of methyl (-CH3) groups to C nucleotides (as well as chemical changes to histone proteins) in order to silence a given gene. If the process of transmission of these features to the next generation, which affects all the progeny of the transmitting parent, depends on the sex of the parent who transmits the gene, which of the following must be true? A. Methylation of C is permanent in a gene. B.Genes required for early development stages must not be imprinted. C.Methylation of this kind must occur more in males than in females. D.The imprints are transmitted only to gamete-producing cells. E. Methylation must be reversible i ovarian and testicular cells.
