NURS 6630 week 2 Discussion Foundational Neuroscience | 100% Verified. Explain how the role of epigenetics may contribute to pharmacologic action. Epigenetics focuses on alterations and modification of genes, including methylation, acetylation, phosphorylation, and ubiquitylation of DNA and histone proteins (nucleosomes), and chromatin remodeling results in disorders like cancer and degenerative diseases (Rasool et al., 2015). Rasool et al. noted that factors like nutrition and the environm...
