Prove that for any integer n \geq 3, n≥ 3, a set with n elements has n (n − 1) (n − 2)/6 subsets that contain exactly three elements. Verified answer. WebThough certain cis-acting elements can effectively prevent the methylation of DNA, other sequences can enhance DNA methylation. For example, Mummanemi et al. ( 96 ) showed conclusively that a cis-acting element located 1.3 kb upstream of the mouse aprt gene acted as a signal for the methylation and epigenetic inactivation of the gene.
