Watson Crick Franklin and Wilkins

I was doing this question for my year 12 biology practical assignments...

German biochemist Johann Friedrich Meicher found nucleic acids were made of a sugar, phosphoric acid and several nitrogen-containing bases. Later it was found that the sugar in nucleic acid can be ribose or deoxyribose (DNA and RNA)

Russian scientist Pheobus Levene discovered the order of the nucleotide components (phosphate - sugar - base). He did this by breaking down nucleic acid in yeast.

there are many other people as well like Rosalind Franklin or Maurice Wilkins

Hope this helped

DNA wasn't discovered in 1953. It was discovered in, depending on exactly what you count as "discovery", either 1869 or 1878.

What happened in 1953 was that James Watson and Francis Crick (there's a good possibility that Rosalind Franklin may have done more than she got credit for, also) described the actual three-dimensional "double-helix" structure. Frankly, I wouldn't describe this as very important at all compared to, say, the growing realization from the late 1920s to the early 1950s that DNA was the carrier of the genetic code, so you should probably look through your textbook for clues as to what the author felt was "so important" about it.

DNA was discovered much earlier. in 1953 Watson & Crick proposed a double helical structure for it to explain the mechanism of replication and trascription etc.

Before resigning from the CSH Laboratory in 2007, he lived in Cold Springs Harbor, New York. Since he and his family had been in that city for over 30 years, it is possible that he is still living there.

The pattern in the DNA structure is known as the double helix, where two strands of DNA are coiled around each other in a twisted ladder-like structure. These strands are composed of nucleotides that form base pairs (adenine with thymine, and cytosine with guanine) connected by hydrogen bonds. This pattern allows for the accurate replication of DNA during cell division.

My DNA appears as a double helix, just like the structure I have learned about. The double helix is made up of two intertwining strands that contain genetic information in the form of sequences of nucleotide bases (adenine, thymine, cytosine, and guanine). This structure allows for the storage and transmission of genetic information during cell division and protein synthesis.

Think he's living in Cold Springs, Long Island, NY.

Watson and Crick's DNA structure supported Chargaff's rules by showing that the base pairs are complementary and form specific hydrogen bonds (A with T and G with C), consistent with Chargaff's observation. This structure provided a molecular explanation for Chargaff's rule that the amount of adenine equals the amount of thymine and the amount of guanine equals the amount of cytosine in DNA.

Francis Crick was a British molecular biologist who is best known for his role in discovering the structure of DNA. He was a prominent figure in the field of molecular biology and made significant contributions to our understanding of genetics and the central dogma of molecular biology.

There are 7 nitrogen atoms in the base pair A-T.

Francis Crick and James Watson used existing data and research, particularly X-ray diffraction images of DNA by Rosalind Franklin, to build models of the DNA molecule. They proposed the double helix structure of DNA in 1953, which revolutionized our understanding of genetics and heredity. Their model explained how genetic information is stored and replicated in living organisms.

James Walker Fannin, Jr. was the Colonel of the Texas Army during the Texas Revolution of 1835-36. Fannin and his men were outnumbered and executed by the Mexicans at the Battle of Coleto Creek.

The discovery that transformation was mediated by DNA was made by Oswald Avery, Colin MacLeod, and Maclyn McCarty in 1944 with their experiments on pneumococcus bacteria. They showed that DNA was the substance responsible for genetic transformation, contradicting the previously held belief that proteins were the carriers of genetic information.

Yes, there is a building named after James Watson at the Cold Spring Harbor Laboratory in New York, called the James D. Watson Building. Additionally, there is a public high school in Dallas, Texas named the "School of Health Professions at Yvonne A. Ewell Townview Center", which is often referred to as the "Watson School of Health Professions."

James Watson was a young American biologist with a background in genetics who was full of energy and ideas, while Francis Crick was an older British physicist with a strong theoretical understanding of crystallography. Together, their complementary skills and perspectives allowed them to collaborate effectively and make breakthroughs in understanding the structure of DNA. Their different backgrounds and approaches made them both unlikely partners and a perfect team for this monumental discovery.

Linus Pauling's work on the structure of proteins, particularly his proposal of the alpha helix structure, influenced Watson and Crick's thinking and approach when they were working on the structure of DNA. Pauling's reputation as a prominent chemist at the time also motivated Watson and Crick to quickly solve the DNA structure before he did.

They were an unlikely pair because of their 12-year difference in age, but still had a strong friendship and working relationship.

your welcome,

P.S- I'm working on the same thing

Watson was an American biologist and Crick was a British physicist, making them an unlikely pair due to their different scientific backgrounds. However, their complementary skills and shared interest in solving the structure of DNA brought them together to collaborate on groundbreaking research. Together, they were able to combine their expertise to make the historic discovery of the double helix structure of DNA.

Francis Crick and James Watson proposed the double helix model of DNA in 1953. This model revolutionized our understanding of the structure of DNA and its role in heredity.

James Watson is best known for his role in the discovery of the structure of DNA with Francis Crick, which laid the foundation for modern molecular biology. This discovery has had a profound impact on fields such as genetics, medicine, and biotechnology, revolutionizing our understanding of how genetic information is stored and transmitted in living organisms.

Rosalind Franklin's work on X-ray diffraction images of DNA was instrumental in the discovery of the DNA double helix structure by Watson and Crick. Her research laid the foundation for our current understanding of genetics and molecular biology. Franklin's contributions have had a lasting impact on science and medicine, advancing our knowledge of genetics and DNA.

Franz Bauer's discovery of apomixis in plants highlighted the concept of asexual reproduction in nature, a concept that was crucial in the understanding of plant genetics. This discovery laid the groundwork for Watson and Crick's work on the structure of DNA by demonstrating alternative forms of reproduction and genetic inheritance. Additionally, Bauer's findings helped pave the way for further research into the molecular mechanisms underlying genetic inheritance.

Robert Hooke's work on microscopy and his observations of cells laid the foundation for the field of cell biology and our understanding of the structure of living organisms. His detailed illustrations and descriptions of cells were important inspirations for Watson and Crick in their research on the structure of DNA, as they sought to understand the molecular basis of life. Hooke's work helped Watson and Crick appreciate the complexity and importance of the internal structure of cells, which ultimately contributed to their discovery of the double helix structure of DNA.

One of the most notable things named after James Watson is the DNA double helix structure, known as the Watson-Crick model after Watson and his collaborator Francis Crick. Additionally, several research institutes and buildings have been named after him, such as the Watson School of Biological Sciences at Cold Spring Harbor Laboratory.

James Watson offended the memory of Rosalind Franklin by reducing her contributions to the discovery of the DNA structure in his book and interviews. He portrayed her in a negative light, focusing more on her personality and appearance rather than giving credit to her scientific achievements. His actions contributed to downplaying Franklin's role in the discovery and overshadowing her scientific legacy.

Watson and Crick asked two key questions in their quest to unravel the structure of DNA: 1) What is the three-dimensional structure of DNA? and 2) How does DNA replicate to transmit genetic information? They answered these questions by proposing the double helix structure of DNA and elucidating the mechanism of DNA replication.
