My first nucleotide is Guanine.how to label all the components with proper atoms and numbering system.
Thanks in advance
In standard numbering convention, aromatic bases are numbered 1-9 for guanine (purine), and the ribose sugar numbered 1' - 5'. Atoms or groups attached to the base or sugar rings atoms have the same number as the ring atom to which they are bounded.
