If the DNA Sequence Remains Unchanged, Why Does Gene Expression Change? Core Mechanisms and Research Methods of Epigenetic Regulation

Most somatic cells in the human body contain essentially the same deoxyribonucleic acid (DNA) sequence, yet different cells differ in morphology, function, and gene expression patterns. Hepatocytes express metabolism-related genes; neurons express genes involved in synaptic transmission; ...

A Functional Systems Review of Cellular Nucleic Acid Metabolism and Regulatory Enzymes in Gene Expression, RNA Homeostasis, and Immune Defense

Intracellular nucleic acids are not static carriers of genetic information, but rather dynamic molecular systems that continuously undergo synthesis, processing, modification, transport, recognition, degradation, and reutilization.
