How did rosalind Franklin help with DNA?

Answer 1

She didn't discovered the DNA. She contributed to the understanding of its structure.

DNA was first isolated by Friedrich Miescher in 1869.

Answer 2

Rosalind Franklin helped Watson and Crick view DNA by the use of x-rays. Her x-rays helped Watson and Crick build a model of a DNA molecule made out of tin that helped scientist better understand the structure of DNA.

Answer 3

She discovered the first ever picture of DNA using x-ray diffraction. Using this picture, she was able to find that it was a double-helix structure. Watson and Crick stole her idea, because female scientists were looked down at in those times and nobody cared, and created the double-helix model and got all of the credit. Without the images Watson and Crick STOLE from her, they wouldnt of been able to produce their molecular model of DNA

Answer 4

Rosalind Franklin's work in X-ray crystallography provided critical data that contributed to the discovery of the DNA double helix structure by James Watson and Francis Crick. Her images of DNA fibers helped Watson and Crick piece together the structure of DNA, even though her contributions were not fully recognized at the time of the discovery.

Answer 5

She took the X-ray fraction photo of DNA , Which helped Watson & Crick to determine the structure of DNA ( B-DNA ) .
