Answer:
Sequence of bases.
Step-by-step explanation:
The DNA molecule can carry a vast amount of hereditary information in its sequence of nitrogen bases. There are four types of bases, adenine (A), thymine (T), guanine (G) and cytosine (C), they convine in different sequences of 3 bases called codon and in a complementary way with the parallel chain of DNA (A-T and C-G) to storage information.
