The correct answer is - inactivity of genes.
Explanation:
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.
<span>Decomposers break down dead
or decaying organisms, and in doing so, convert their basic materials
into forms more useful to the biological community, particularly plants.
The main decomposers in the environment include bacteria, fungi and
worms. Each of these plays a different, but overlapping, role in
decomposition</span>
