21 Sep Science Tuition on Rosalind Franklin
Hi and welcome back to your Science Tuition. We are never out of facts and information for our chemistry lovers out there. Hope you have been enjoying our lessons.
Continuing with the Science Tuition lesson on the famous chemists, today we will learn more about Rosalind Franklin.
Rosalind Franklin was born on 25th July 1950. She is from England and is a renowned chemist famous for her pioneering work in the field of X-ray crystallography.
During one of her studies, she acquired the knowledge about the technique of x-ray crystallography, and she was intrigued by its scope, and that is when she decided on pursuing a career in this field. To understand the changes occurring at the molecular level in carbon when its state is changed, she used the x-ray imagery of coal. And later she presented her significant discovery which was on the structure of the DNA molecule.
Lets us take a look at some lesser known facts about her.
Before DNA, she studied the holes in coal. After completing her college, Rosalind Franklin pursued a doctoral degree from Cambridge, and since this was during World War II she worked on the porosity of coal for fuel purposes and other wartime devices.
Rosalind Franklin captured photograph 51. It shows that DNA is helical. In her conclusion, she stated inconsistency with the model proposed by Watson and Crick. Prior to the publication of her paper, they were shown to Crick without Franklin’s consent which is till date a hugely controversial issue.
Franklin loved traveling and backpacking. Her favorite country was France and she frequently traveled there and backpacked through the French Alps.
Rosalind Franklin worked till her last breath. She was diagnosed with ovarian cancer and started chemotherapy in 1956. She published seven scientific papers in 1956 and six more papers in 1957 even when she was having chemotherapy.
She was not appreciated much in her time but she is a very celebrated name in Science in today’s time.
That is all for today in Science Tuition. Stay tuned to know more.
