A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA

Explanation:
1. Epigenetic modification:Those changes which do not involve the alterations in the sequence of DNA, means there in no change in DNA sequence, like addition, deletion or such other type of changes in the sequence of nucleotide do not occur
2. Epigenetic describes any such type of modification of chromosome( which do not change the sequence of nucleotide), especially histone modifications, and these changes may be heritable or not or associated with a phenotype.
The metabolism of glucose involves the breakdown of glucose molecules to form the needed energy by the cell called ATP.The process follows the order of;
