In 1869, Friedrich Miescher isolated a new molecule from the cells’ nuclei and called it “nuclein.” Nuclein contained hydrogen, oxygen, and a unique ratio of phosphorus to nitrogen.
His work provided the groundwork for many DNA discoveries to come since it was now possible to distinguish a part of a cell from the entire thing.

In 1952 Rosalind Franklin created Photograph 51 showing a distinctive pattern that indicates the helical shape of DNA.
Her work was important because it gave other scientists answers or help on their work. It also gave them a picture of how the structure is.

Watson and Crick are the two scientists that found out about DNA and how the structure was formed.
Their work is important because it gave every scientist information about DNA.They also gave all the scientists the form of a DNA strand.

DNA is made of nucleotides.  Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.

The nucleotides of DNA are sugar deoxyribose, one of four bases cytosine ,thymine T , adenine A , guanine G , and a phosphate.
Nucleotide is a compound consisting of a nucleoside linked to a phosphate group.
