A group presentation on a famous scientist.

1. Rosalind
Franklin
1920-1958
By Madihah and Marwa
• Born in London to an affluent family in 1920.
• She graduated in 1941 with a degree in natural sciences
from Newham College, Cambridge.
• She got her PhD in physical chemistry at the University
of Cambridge.

2. • In Paris, Franklin worked with
crystallographer Jacques Mering in 1946.
• In 1951, she worked at Kings College
London in the biophysics unit and studied
DNA with x–ray diffraction.
• Franklin and her student Raymond
Gosling, discovered that there were two
forms of DNA by taking pictures, which
became critical evidence in identifying the
structure of DNA. They acquired the
photo by a 100 hours of x-ray exposure
from a machine Rosalind had refined.
They published the the first evidence of a
double helix.
• She then went on to explore RNA, again
using x-ray crystallography to study the
tobacco mosaic virus, which she proved
all virus particles were the same length.
• She worked on the polio virus in 1957
where she was attempting to to study the
virus through x-rays, she had to stop due
to her worsening health.
