Early lifeStimson grew up in a Catholic family of English and Irish descent, the third child of Mary Holland and Frank Stimson. Her early life was surrounded by illness; her older brother had polio, and her younger sister contracted a bacterial infection that affected her heart. Complications from the birth of twins left her mother with high blood pressure that affected her memory. Stimson helped raise her younger siblings, looking after her younger sister and teaching her to read. This experience shaped her personality as an educator.[2] Stimson attended to a small religious school in Michigan. She was working on the experiment about how "wound-healing hormones and even helped to create a note hemorrhoid cream (preparation H)" all that was finding before her hobby in studying the DNA bases and shape.[5] She was a Professor of chemistry in a number of schools.[2] Education and careerAlthough Stimson's family were Catholic, and her parents were encouraged her siblings and her to learn about their religion, Stimson took an interest in science. Frank and Mary Stimson supported their children in their desire for education despite the fact that women were marginalized. When Stimson reached the age of fourteen, her parents sent their daughters to St. Joseph College And Academy, a Catholic academy in Adrian, Michigan, run by the Adrian Dominican Sisters. After graduating she worked at St. Joseph College. She joined the Adrian Dominican Sisters and completed her education at Siena Heights College. After graduating she taught at Siena Heights College in Adrian and attended graduate school at the Institutum Divi Thomae.[2] Stimson taught chemistry at Siena Heights University and served as an academic advisor.[2] Structure of DNAThere is a book for Dr. Jun Tsuji under title The soul of DNA its the story of Sister Miriam Stimson and her knowledge about DNA and double helix, and she illustrated the structure of DNA in the easy way to understand. She also explained the relationship between cells and chemical instructions.[2] Sister Miriam's developed the 'KBr(Potassium Bromide) disk technique' in which she mixed samples with KBr and compressed it into little disk. KBr (Potassium Bromide) was a reasonable substance that wouldn't interfere with the infrared light, and furthermore it is ready to meld effectively with the example. Sister Miriam's technique was demonstrated to be superior to previously used oil method in a number of ways; “there was an absence of interfering bands, lower scattering losses, higher resolution of spectra, better control of concentration and homogeneity of sample, ease in examining small samples, and possibility of storing of specimens for further studies” (qtd. in Tsuji 120).[2] This sort of method would have the capacity to accomplish a more exact spectrum of the compounds inside a substance and their position, which would alter infrared spectroscope for quite a while, and furthermore affirm the Watson - Crick Model of the double helix for DNA. Because of her discoveries, Sister Miriam added to one of the best disclosures in her century, and in this way enabled facilitate examination to keep including DNA structure and cancer, giving different researchers a more precise view on how DNA framed and worked.[2] References1. ^Cath News {{authority control}}{{DEFAULTSORT:Stimson, Miriam Michael}}2. ^1 2 3 4 5 6 7 {{Cite book|title=The Soul of DNA: The True Story of a Catholic Sister and Her Role in the Greatest Scientific Discovery of the Twentieth Century.|last=Tsuji|first=Jun|publisher= Llumina|year=2004|isbn=|location=Florida}} 3. ^Obituary in the Toledo Blade 4. ^{{cite book|author1=A.
