DNA looks like a ladder that has been twisted into a spiral. This shape is referred to as a helix shape.
The first picture and model of the DNA structures were made from Rosalind Elsie Franklin. Over the years William Watson and Francis Crick stole the idea from her and worked out the structure of DNA as if they invented it.
F, Crick and j.Watson discovered the structure of DNA.
were the first to describe the hidden double-helix structure of DNA molecules
it was in strands
1950
Chromosomes are an organized structure of DNA and protein that is found in cells.
they put pieces together
a DNA molecule is made up of a phosphate, sugar and base A double Helix Strand

Before Watson and Crick could discover the shape of DNA, Swiss chemist Friedrich Miescher had to discover DNA in the first place. Later, Phoebus Levene and Erwin Chargaff would begin investigating the structure of DNA.
1950
The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
