DNA Rosalind Franklin: The Story of a Great Discovery

Have you searched the web for "DNA Rosalind Franklin" because you want to know more about this topic? Read this article where we will explain the discoveries of the famous scientist.

Who is Rosalind Franklin ? Have you ever heard of her story? The story of a great discovery that changed the world of science forever.

Rosalind Franklin was born on 25 July 1920 in Notting Hill, a district of London, she was a chemist and x-ray crystallographer.

She was a passionate researcher, her studies were fundamental for the understanding of the molecular structures of DNA.

The dedication she showed since she was a child and her strong passion for scientific subjects made her one of the greatest scientists of all time.

The structure of DNA

A solid background in crystallography allowed her to apply her knowledge to one of the great unknowns of the time: the structure of DNA .

Through the extraordinary images she obtained it was possible to observe the helical shape that we all know today.

The inspiration of the brilliant Rosalind Franklin was immediately linked indirectly to the great names of the discipline to which she chose to dedicate herself, such as Albert Einstein . She even attended the same university where Isaac Newton had studied three centuries earlier.

Rosalind Franklin, through her cryptography skills, manages to perfect the X-ray diffraction of DNA, discovering its two forms A and B, a decisive step in the study of its structure.

His skill in preparing chemical preparations and X-ray analysis had provided the first clear picture of DNA. Yet, someone tried to appropriate his findings...

The relationship between Franklin, Watson and Crick

Rosalind Frankin's discoveries were unknowingly detected by James Watson and Francis Crick, "colleagues of Franklin's study" who tried to extract some information from him. In November 1951, the two created a first DNA model taking into account the information they had obtained and the reflections of the young Franklin.

Unfortunately, this led to a rift between the parties and where Franklin's great contribution was never recognized. James Watson and Francis Crick used the images and some of his deductions to publish the article.

Deceived and disappointed after the publication of Watson and Crick's results, Rosalind Franklin dropped out of college but not from research. She concentrated her efforts in virology , making decisive contributions to the molecular structure of viruses. Her discoveries are still considered in current research.

The Travels and Illness of Young Franklin

The esteem she had for Watson and Crick and the little gratitude shown after Franklin's discovery, led the young scientist to take a trip to Israel where she began to dedicate herself to the tobacco mosaic virus , a research aimed at understanding the mechanism of infection of the virus.

Despite his reserve, for the first time Franklin managed to establish a good relationship with his new colleagues, with whom he discovered that the analysis of the structure of TMV showed protein molecules in which RNA was present.

His discoveries were vital to the growth of society and a greater understanding of human organisms.

DNA - Why was it such an important discovery?

DNA is the molecule that makes us what we are as human beings, very important nowadays is to also do DNA tests to understand where we have deficiencies and how to intervene on them.

You can learn to know yourself better through your DNA, better understand your intolerances to certain foods, or if you practice sports, an accurate analysis of your nutrition can facilitate the process of staying in shape and having a better performance.

If you want to take a DNA test today, it's actually very simple because you can buy one of our Holifya kits where by simply collecting a sample of your saliva, we will explain your current condition and give you some advice on how to improve your lifestyle.

What can you find out from a DNA test?

Taking a DNA test can be important for many needs and can become essential to achieve certain goals. Let's see together why it is important:

• Ideal macronutrient distribution: allows you to understand how to properly distribute proteins, fats and carbohydrates.
• Foods to assimilate and foods to eliminate: indicates which foods it is advisable to favor and which it is advisable to avoid, in order to counteract genetic predispositions or specific pathologies.
• Ideal meal composition: indicates in what specific order to consume different foods within a meal and the right balanced dose of daily calories between different meals.
• Sport : indications on predisposition for power or resistance sports and cardio-pulmonary properties (VO2max);
• Prevention such as insulin resistance and type 2 diabetes, inflammation and oxidative stress (13 predispositions);
• Skin-aging: collagen structure and remodeling of the dermal matrix (2 predispositions)
