Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)
-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)
