DNA Model DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. The 4 types of nitrogen bases are adenine, thymine, guanine and cytosine. The order of the bases determines the DNA’s instructions. The two strands that make up each DNA are antiparallel to each other, which allows the complimentary base pairing. This structure shows the antiparallel strands, which is accurate to the structure of DNA, to improve the accuracy of this model we…
