DNA is deoxyribonucleic acid , it is the molecule in the living organisms that is responsible for making every species different than the other species and allows its offspring to carry the same characteristics. The DNA is found in the nucleus of every cell of the living organism. The DNA molecule is called the chromosome.
The genes are a sequence of DNA. The gene was discovered by Gregor Mendel (1822-1884) an Austrian scientist, he discovered the genes through his work on the peas starting from the year 1856 till the year 1865.
And so far away the German biologist, Walther Fleming (1843-1905) reached without knowing the work of Mendel the chromosomes in the year 1882.
Frederick Miescher (1844-1895) a Swiss scientist discovered DNA in the year 1869 while working on the chemistry of body blood, he reached the hereditary material DNA, but he didn’t know it. He was able to isolate the DNA and to analyze it, he called the new material “nuclein”
In the year 1950, Linus Pauling (1901-1994) an American chemist and biochemist was able to make the structure of the DNA. But he did not have the credit because of his isolation.
At the same time, there were other researchers working on the same idea and they were able to reach the new discovery of DNA, that was in the year 1951. When James Watson born in the year 1928 the American molecular biologist and geneticist, along with Francis Crick (116-2004) the English molecular biologist and biophysicist, discovered the structure of DNA that we now know.
In the same period in England there were other scientists working on the same subject. Rosalind Franklin (1920-1958) along with Maurice Wilkins (1916-2004) They are both a British biophysicists, they were trying to reach the structure of the DNA as well.
But the credit went for James Watson and Francis Crick as they were the first to spread their structure of the DNA all over the world.
