Why did Rosalind Franklin spend most of her time researching the A type form of DNA?
Rosalind Elsie Franklin had a student working in the DNA - pioneers team. Franklin decided to join her student at work, later taking x-ray diffraction images and discovering the true scructure of DNA. But mainly... Franklin was a microbiologist and also studied chemistry, and under those topics comes molecules & DNA.
What else can I help you with?
What was rosalind Franklin's theory?
She incorrectly theorized that DNA was a triple helix. Watson and Crick used information from Franklin's research to form the correwct model of double-helix DNA.
What was rosalind Franklin famous for?
Rosalind Franklin was a British scientist known for her work in determining the structure of DNA through X-ray diffraction studies. Her data, obtained without her knowledge, played a crucial role in the discovery of the double helix structure of DNA by Watson and Crick.
What country was rosalind Franklin born in?
in London specifically in king's college, where she has worked on the DNA, and then to birkbeck college, where she has worked on the TMV virus, but she haven't stayed there for a long time, but before both of these college she work in some coal association, were she discovered tow form of coal. But I think it is the king's college because it is the place where she has done her most well- know research
What scientist in 1952 discovered that DNA is actually two chains of molecules in spiral form?
James Watson and Francis Crick, along with Rosalind Franklin, made groundbreaking discoveries regarding the structure of DNA in 1952. They determined that DNA is composed of two intertwined chains of molecules in a double helix shape. Their research laid the foundation for our understanding of genetics and heredity.
What led Rosalind Franklin to announce the death of the helix in a note to Maurise Wilkins?
Rosalind Franklin's note to Maurice Wilkins announcing the "death of the helix" was referring to her discovery that DNA did not form a simple helical structure as previously thought. Instead, her research using X-ray diffraction showed a more complex structure, leading to the conclusion that DNA had a more intricate arrangement than initially proposed.

What is the method used for rosalind franklin?
Rosalind Franklin used X-ray crystallography to study the structure of DNA molecules, specifically the B form of DNA. This technique allowed her to produce high-resolution images of DNA fibers, providing crucial data that contributed to the discovery of the double helix structure by Watson and Crick.

What does rosalind mean in latin form?
In Latin Rosalind means 'From the Rose'. P.S. that's such a pretty name!

The work of Rosalind Franklin provided a key piece of data for Watson and Cricks model of DNA Summarize that evidence and how it was pivotal to the correct model being built?
Rosalind Franklin's X-ray diffraction images of DNA revealed a helical structure with a consistent diameter and regular twisting pattern. This data suggested a double helix shape for DNA, which was essential for Watson and Crick in developing their accurate model of DNA's structure. Franklin's evidence provided crucial insights into the physical form of DNA, leading to the correct understanding of its double helix structure.
What two forms of DNA did Franklin discover?
Rosalind Franklin discovered two forms of DNA: the A-form and the B-form. The A-form is a dehydrated version of DNA, appearing shorter and more compact, while the B-form is the more common, hydrated form that is typically found in biological systems. Her X-ray diffraction images provided crucial insights into the helical structure of DNA, particularly the dimensions and orientation of the B-form.
The shape rosalind Franklin uncovered with her x-ray diffraction and Watson and crick memorialized in a model?
The shape is a helical structure known as the double helix, which is the twisted ladder-like form of DNA. Rosalind Franklin's x-ray diffraction images provided crucial evidence for the structure, and Watson and Crick built a model to accurately represent the DNA molecule's double helix shape.
Why did Franklin concentrate on the A form of DNA?
Rosalind Franklin concentrated on the A form of DNA because it provided clearer and more distinct X-ray diffraction patterns compared to the B form, which was more challenging to analyze due to its less organized structure. The A form is also more stable under certain conditions, allowing Franklin to obtain high-quality images that were crucial for understanding DNA's helical structure. Her work ultimately contributed significantly to the discovery of the DNA double helix.
Did Rosalind Franklin know that DNA was a helix?
Yes, Rosalind Franklin deduced that DNA had a helical structure based on her X-ray diffraction images, particularly the famous Photo 51. Her meticulous work revealed key features of DNA, including its width and the presence of a helical form. However, she did not fully understand the implications of her findings in the context of the double helix model until after Watson and Crick published their work, which was based, in part, on her data without proper acknowledgment.
