DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

A chromosome is an organized structure of DNA and protein that is found in cells. A chromosome is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences.he difference between DNA and a chromosome has to deal with an intermediary-genes. DNA is deoxyribonucleic acid, which is a nucleic acid. It is made up of four bases-adenin â¦ e, cytosine, guanine and thymine. When these four bases are arranged in a segment, it is called a gene.
