DNA Modification Mechanisms
Acetylation and methylation are crucial biochemical processes that regulate gene transcription by altering the structure of DNA. Acetylation relaxes chromatin, facilitating gene activation, while methylation condenses it, inhibiting transcription. These modifications are influenced by complex intracellular signaling cascades, ultimately determining gene accessibility and expression levels. Understanding these mechanisms is essential for grasping how genes are turned on and off within the cell.In this clip
