If our genes have 4 BASES, how is DNA Deoxyribonucleic ACID?

The bases themselves are, in fact, basic. They do have higher than neutral PH. However, this is offset by the fact that they're very WEAK bases, and they're bound to a phosphate group, which acts as phosphoric acid (a relatively strong ACID). As such, the entire DNA molecule has a decidedly low PH.

De- = remove

oxy = oxygen

DNA is called deoxy- because it has the sugar deoxyribose, instead of the sugar ribose, which is found in RNA.

"Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H−(C=O)−(CH2)−(CHOH)3−H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom."
