🧬 Nucleic Acids

Nucleotides form nucleic acids


Nucleic acids are polymers of the nucleotide monomer and include the central biological molecules DNA (deoxyribonucleic acid), RNA (ribonucleic acid) and ATP (adenosine triphosphate), playing roles in inheritance, protein synthesis and metabolism.


ATP is adenosine triphosphate, a nucleotide involved in metabolism and many biological processes (the molecular energy currency).


A nucleotide is a molecule composed of a pentose sugar, an organic base and at least one phosphate group.



Chemical energy is important in biological processes because it helps maintain the many reactions that go against a natural equilibrium. These include movement of chemicals against a concentration gradient via active transport, enabling enzyme action as ATP acts as a…
