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.
The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers. They are all important parts of an ecosystem. Producers are the green plants. They make their own food.
Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. A small amount of nitrogen can be fixed when lightning provides the energy needed for N
