phosphate groups and sugar molecules.
The phosphate groups are all the same and are the backbone that connect the chain together.
The deoxyribose is the sugar and is the same for all the bases. It lies between the phosphate and the nucleotide.
The bases are different from each other. There are 4, A, C, G, and T.

DNA is deoxyribose nucleic acids. they are consist of nitrogenous bases (which are adenin A, guanine G, cytosine C and thymine T ), deoxyribose sugar molecules and phosphate groups. these 3 types of molecules have different structures. DNA is 2 stranded structure. 2 stands are connect by hydrogen bonds between A to T and G to C. so amounts of A &T or G & C are identical. but amounts of A & G are not identical.

Phosphate groups and sugar molecules. The nitrogenous bases are what makes them different and unique.
If you want brownie points from your teacher, don't say "sugar molecule", it's "saccharide residue".
