What was linus pauling's contribution to biology?
Linus Pauling was a chemist who made significant contributions to biology through his work on the structure of proteins, particularly his discovery of the alpha helix. He also proposed the concept of molecular disease, which linked genetic mutations to specific diseases. Additionally, his advocacy for vitamin C as a treatment for various illnesses impacted the field of biochemistry.
The Bohr model of atomic structure?
Niels Bohr propose a planetary model for the atomic nucleus.
What was the first DNA model called?
The first correct shape was the double helix by Watson and Crick. However, there were earlier incorrect models, for example the incorrect triple helix model proposed by Linus Pauling. Even the first model by Watson and Crick turned out to be incorrect; they had it inside out compared to the correct model.
What is the difference between Pauling's structure and the actual structure of DNA?
Pauling's structure of DNA, proposed in the early 1950s, presented a triple helix model with bases on the outside and phosphate groups in the interior, which was inconsistent with known biochemical properties. In contrast, the actual structure of DNA, elucidated by Watson and Crick, is a double helix with two strands running antiparallel, where the nitrogenous bases pair specifically (adenine with thymine, and cytosine with guanine) on the inside, stabilized by hydrogen bonds. This accurate model accounts for the mechanisms of genetic replication and transmission. Pauling's model was ultimately proven incorrect due to these fundamental differences in structure and function.
Watson and Crick elucidated the structure of DNA in 1953 Their research built on and helped explain the findings of other scientists including?
Rosalind Franklin's X-ray diffraction images which provided key insights into the structure of DNA. Maurice Wilkins also contributed to the discovery by working on the same subject as Franklin. Linus Pauling's work on the nature of chemical bonds was also influential in shaping Watson and Crick's model of DNA.
Which scientist added an extra strand to the structure of DNA and won two Nobel Prizes?
Linus Pauling is the scientist who proposed a triple helix structure for DNA with an extra strand. However, this model was later proven incorrect. Linus Pauling won the Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962.

Why did Watson and Crick succeed when Pauling failed?
Watson and Crick succeeded in determining the structure of DNA because they were able to use X-ray diffraction data from Rosalind Franklin and apply it to their model-building techniques. Pauling, on the other hand, incorrectly proposed a triple-helical structure for DNA due to the data available to him at the time. Watson and Crick's collaboration and access to critical data were key factors in their success.
In what year did Rutherford propose his atomic model?
1908.
Linus guitar Model No LL 100SN. Anyone heard of this make of Korean guitar?
I have not heard of this specific model, but I have a Linus Model LSC45 handmade by Linus Music in Dongduchon, South Korea. I was stationed there some years back, and went exploring downtown. I found the store front and walked in, played a guitar hanging on the wall and fell in love with it. Had the same model made in the store with a few changes, and paid a very low price for it.
What model of our solar system did Copernicus propose?
heliocentric system
The Bohr model of atomic structure?

Even the first model by Watson and Crick turned out to be incorrect; they had it inside out compared to the correct model.
Watson and Crick knew that the triple helix model of DNA that Linus Pauling had proposed was incorrect What evidence did they have for such a conclusion?
Watson and Crick had evidence indicating that the width of the DNA molecule suggested a double helix rather than a triple helix. Additionally, base pairing rules they proposed provided a more plausible explanation for the structure of DNA. These findings led them to conclude that the triple helix model was incorrect.
When did Ernest Rutherford propose the plum pudding model of the atom?
The ''plum pudding atomic model" is from J. J. Thomson, year 1904.
Which model propose that from an early age people are active and in control of directing their own development?
stage
What Make and Model is the Linus Larabee Private Jet in the movie Sabrina?
In the movie "Sabrina," the Linus Larabee private jet is depicted as a sleek, luxurious aircraft, specifically a 1950s model of the Douglas DC-6. This aircraft symbolizes the wealth and sophistication of the Larabee family. The film uses the jet to emphasize the contrast between the characters' affluent lifestyle and Sabrina's more modest background.
