Understanding Epigenetics: DNA Methylation and Histone Modification
Epigenetics involves modifications that impact gene expression without altering DNA sequences, playing a crucial role in the transition from genotype to phenotype. This includes DNA methylation, histone modification, and microRNAs. DNA methylation, controlled by DNMT enzymes, can lead to either gene
