The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.
The nucleic acids must have positive charge that helps in formation of double helices.
Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.
