Rosalind Franklin Rosalind Franklin helped contribute to one of the greatest breakthroughs in science. She was born in London in 1920 and she was raised by a very wealthy and educated family. Rosalind Franklin was easily described as hardworking and the best at everything - the best at science, at math, and at all the other sports she participated in. Franklin arrived at King's College London, and in January, 1951, her new assignment was to discover the structure of DNA. At the time when Rosalind Franklin started working on DNA, it wasn't at all clear what DNA really looked like or how it might work. Franklin did most of the professional work in the lab and she was able to capture excellent pictures of DNA. Within that time, Franklins discovery that there are two forms …show more content…

After watching this video, I learned that from the DNA structure, the A is a drier, more crystalline form of DNA and produces more detailed images. The B is wetter and how DNA occurs in living cells. The X shape in the middle is the diffraction signature of a helix. I found it very interesting how we understood the concept of DNA back then and we realized how important it was being that it contained genetic material and the blueprints for every cell in our body, yet we still needed to explore what it really looked like and how it worked. This is related to the things we have covered in class because we have already studied DNA. In this course, we have studied the many characteristics of DNA which include that it is double helix that contains genetic material and it is kept stable by hydrogen bonds. DNA is made up of smaller units called nucleotides. In turn, each nucleotide consists of a phosphate group, a sugar and a nitrogenous base. DNA also include base pairing which is the 'copying' mechanism for DNA. In DNA, bases are the adenine base, which only pairs with a thymine
