Parts and their functions

• Phosphate (फ़ॉस्फ़ेट) — Phosphoric acid esterified to the sugar; links nucleotides by phosphodiester bonds.
• Sugar (शर्करा) — Pentose: ribose (RNA) or 2′-deoxyribose (DNA).
• Nitrogen base (नाइट्रोजनी क्षारक) — Heterocyclic ring: purines A, G; pyrimidines C, T, U.
• Nucleoside = sugar + base (न्यूक्लियोसाइड = शर्करा + क्षारक) — e.g. adenosine, guanosine, cytidine, uridine, thymidine.
