DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).

I believe that the chemical buffers provide the shortest term mechanisms for preventing acid-base imbalances in the body. Chemical buffers normally act within a fraction of a second to resist a pH change. On the other hand the longest mechanism is the kidney system which ordinarily requires from several hours to a day or more to affect changes in blood pH.
