James Watson and Francis Crick are usually credited with the big breakthrough, though their work was built on that of others, including Maurice Wilkins and his team. This was recognised when Wilkins shared the Nobel prize with them. Many people credit Rosalind Franklin with an important part of the work too, but she died before the prize was awarded.
Frederick Miescher - is the man who discovered DNA. The Swiss physician isolated a high phosphorous-containing substance from white blood cell nuclei in 1869. It was DNA, which he called 'nuclein' because it had come from the nucleus. He did not know its true nature.
Phoebus Levene - the Russian-American biochemist discovered the order of components of nucleic acids; phosphate-sugar-base. He coined the term 'nucleotide.' He also discovered the ribose sugar in RNA, the deoxyribose sugar in DNA, as well as identifying the way the nucleic acids - RNA and DNA - are put together.
Oswald Avery - in 1944 he discovered that DNA transmitted hereditary information. This was a revolutionary concept, because the scientific consensus at the time was that DNA was too simple for this task, and that proteins were more likely to be the candidates.
Erwin Chargaff - in 1950 he demonstrated that the nucleotide composition varies amongst species. This was different from Levene's view that the same nucleotides repeat in the same order. He also found that in any given species the ratio of adenine to thymine was roughly equal, and the ratio of cytosine and guanine was also roughly equal. This is known as Chargaff's rule and it helped to pave the way for Crick and Watson's studies.
Rosalind Franklin - her X-ray diffraction image of DNA structure, named 'Photo 51' was a significant piece of evidence in determining DNA structure. She was briefly mentioned in Crick and Watson's proposal of the double helix structure in the journal Nature in April 1953. Watson, Crick, and Wilkins shared the Nobel Prize in Physiology or Medicine in 1962 for their work. Franklin was not acknowledged because she had died by this time and the award cannot be given posthumously. The significance of her role in DNA structure discovery was only realized after the publication of Watson's book The Double Helix in 1968.
Linus Pauling - the methods he used to work out the structure of proteins were adopted by Crick and Watson. They were a combination of model building, chemistry, and physics.
Maurice Wilkins - obtained the first X-ray image of DNA. He taught Francis Crick about DNA, and his images of DNA inspired James Watson. He shared the 1962 Nobel Prize in Physiology or Medicine with Crick and Watson.
Francis Crick and James Watson - published their paper in Nature, in April 1953. It was one of the most important pieces of research in the history of science.

What are two ways that's scientists can study earths climates history
Yes, DNA is double-stranded.There are two strands. Each one is a polymer (series) of nucleotides, and the two strands twine round one another to form the DNA molecule.
Louis Pasteur was the first man to stumble across the germ theory, and was discovered in 1861. This then led to many other diseases being found as everyone know knew that germs caused disease. Robert Koch was one of these scientists and he found the cure for two of the most deadliest diseases from the time: cholera and TB (tuberculosis), with the help from a microsope he was able to isolate the germ that caused the disease and so other scientists could then work on how to cure the diseases.
Meselson and Stahl
Arithmetic progression was invented and discovered by two different mathematicians and scientists. Their names were Harvey Dubner and Tony Forbes.
They discovered the DNA structure
The structure of DNA was discovered by Watson and Crick
Two scientists discovered DNA. They announced that they found the building blocks of life. Well it is the building block of life. In a single human cell if you can take out all the DNA and stretch it, it will be two meters.
E.S. Barghoorn and J.W. Schopt(1965) are the names of two scientists, who discovered the two millon years old ancient bacteria.
Two very significant discoveries happened in that interval. It was discovered(using viruses) that DNA was the genetic material IT was discovered (using radioisotopes and a method called gradient centrifugation) that DNA replication is semi-conservative In 1953, Dr. James Watson, Dr. Francs Crick, Dr. Maurice Wilkins and Dr. Rosaling Franklin together discovered the double helical structure of DNA. However, the former two scientists are credited for the work.
two different mathematicians and scientists
Scientists have discovered two moons.
Rosalind Franklin discovered that DNA has the shape of a double helix by using x-ray technology. However, two scientists got the credit for discovering the double helix shape of DNA, James Watson and Francis Crick. Watson and Crick get the credit for discovering the double helix shape because Rosalind Franklin died in 1958, and the first Nobel prize for discovery wasn't awarded until 1962.
The two scientists to establish DNA are James Watson and Francis Crick.
The DNA undergoes a process named PCR (Polymer Chain Reaction) once the scientists get a hold of the DNA. essentially the DNA double helix is unwound and is split into its two strands, and random nucleotides (or primers as they are called in this process) attach to the two open strands. These primers form hydrogen bonds with the DNA strands. due to this, there are now two strands of DNA rather than just one. scientists do this over and over again, until they have enough DNA to be able to test whatever they need to test on it.
