It focuses particularly on biological molecules such as DNA, RNA, proteins, carbohydrates, lipids, and enzymes. Molecular biology helps explain how genetic information is stored, copied, expressed, and regulated inside living organisms. It is closely connected with genetics, biochemistry, biotechnology, and modern medical research. […]

It is tightly regulated and essential for protein quality control, metabolic regulation, cell‑cycle progression, and stress responses. Without efficient degradation systems, cells would accumulate defective proteins, leading to toxicity, impaired signalling, and disease. Protein degradation is therefore a central concept in cellular homeostasis and molecular biology. […]
