Epigenetic Control of Gene Expression

Gene expression is partly controlled by epigenetic changes.
Epigenetics impacts transcription and translation.
Epigenetics involves heritable changes in gene function without altering the base DNA sequence.
These epigenetic changes are triggered by environmental changes.
Epigenetic changes inhibit transcription via increased methylation of the DNA or decreased acetylation of associated histones.
Specific understanding of how methylation impacts each gene is not necessary.
It is important to understand that certain factors can result in epigenetic changes.
The impact of epigenetic changes should be inferred from given situations.
