DNA methylation is a process in which the DNA molecule is attached to the methyl groups. Methylation affects the activity of the segment of DNA without modifying or changing the sequence of the gene.
If methylation takes place within the promoter region of the gene, DNA acts as a repressor for the process of gene transcription. Inactivity of the gene is by the help of methylation in the eukaryotes is to control the gene expression.
Thus, the correct answer is - inactivity of genes.
