Answer:
Sequence of base along its strands
Explanation:
Deoxy ribonucleic acid (DNA) is a double-helical structure made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The nitrogenous bases found in DNA structure are four viz; adenine (A), thymine (T), guanine (G) and cytosine (C). These bases are the same in almost all individuals but the order or sequential arrangement of these nitrogenous bases is what determines the instructions given to a specific DNA or genetic code, which is actually the basis of difference between each DNA molecule.
