Nucleic acids and ribosomes

Nucleic acids and ribosomes constitute the essential apparatus for the storage, transmission, and expression of genetic information. Nucleic acids, comprising deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), serve as the templates for life, while ribosomes are complex ribonucleoprotein machines responsible for translating genetic codes into functional proteins (Wilson, D. N., Nature Reviews Microbiology, 2014 [1]). In clinical practice, these entities are major therapeutic targets, particularly for antibiotics that exploit structural differences between prokaryotic and eukaryotic ribosomes to selectively inhibit bacterial protein synthesis (StatPearls, "Physiology, Ribosome", 2023 [2]). Additionally, many antineoplastic agents target DNA through intercalation, alkylation, or by inhibiting topoisomerases, thereby inducing DNA damage and apoptosis in rapidly dividing cancer cells (Pommier, Y., Nature Reviews Cancer, 2006 [3]). While highly effective, drugs targeting these systems often face challenges such as the development of molecular resistance and off-target toxicity, particularly when therapeutic agents cross-react with human mitochondrial machinery (Neidle, S., Nature Reviews Drug Discovery, 2002 [4]).
