In 1869 Friedrich Miescher identified "nuclein" from cell nuclei with associated proteins with DNA. Miescher´s work is really important because if he didn't discover the molecule nuclein, we wouldn't know that proteins are the molecules by which traits passed on and on.

Rosalind Franklin created a photograph showing a exclusive pattern that indicates the spiral shape of DNA. Her work is important because she studied the structure of DNA using a X-ray and then was introduced to a 3-D model of a DNA model

The nucleotides of DNA base pair get stuck together by hydrogen bond in a specific way. Adenine will only get together with thymine ( A to T ). Cytosine will only bond together with guanine ( C to G )

Watson and Crick discovered the double helix, with sugars and phosphates. structure of DNA. James and Francis' work is important because they used the bases ( A, C, G, T ) and they were able to pair them up and make two strands of the helix.

DNA is made of two strands of nucleotide. The four bases are called adenine, guanine, cytosine, and thymine. The bases get together using hydrogen bonds.

The nucleotide of DNA are the simple building blocks that make up the DNA. The three parts of nucleotides are phosphate, sugar molecule and one of the four bases.
