Definition: More precisely: nucleic bases. These molecules belong to the basic building blocks of the DNA and code the genetic information. Four bases are used in the DNA which form, in pairs, the rungs of the double helix (Adenine-Thymine; Guanine-Cytosine). 

A class of compounds that are "opposite" to acids, in that they neutralize acids.   Weak bases are used in cooking (baking soda) and cleaners.  Strong bases can be corrosive, or "caustic".  Examples of strong bases that are common around the house are drain cleaners, oven cleaners and other heavy duty cleaning products.  Strong [..]

Compounds that react with acids to form salts plus water. Alkalis are water-soluble bases used in petroleum refining to remove acidic impurities. Oil soluble bases are included in lubricating oil additives to neutralize acids formed during the combustion of fuel or oxidation of the lubricant.

Distinct chemical ingredients found in the genetic material of all life-forms. 

the four organic molecules which are found in nucleotides. The bases found in DNA are adenine, thymine, guanine and cytosine. In RNA, thymine is replaced by uracil.
