epigenetiisiä
Epigenetiisiä are a concept rooted in epigenetics, referring to heritable changes in gene function that do not involve alterations to the underlying DNA sequence. The term is derived from the Greek “epi,” meaning “above” or “over,” signifying modifications that influence gene activity rather than the genetic code itself. These changes are typically mediated by chemical modifications to DNA or histone proteins, such as methylation, acetylation, or phosphorylation, which can alter chromatin structure and regulate gene expression.
Epigenetiisiä play a critical role in development, cellular differentiation, and adaptation to environmental factors. They enable
The heritability of epigenetiisiä can extend across cell generations and, in some cases, across multiple generations
Understanding epigenetiisiä is essential for developing novel therapeutic strategies for diseases such as cancer, neurological disorders,
