What did George Beadle discover?

George Beadle and Edward Tatum proved in 1941 that our genetic code‚ our genes, govern the formation of enzymes. They exposed a type of mold to x-rays, causing mutations, or changes in its genes. They later succeeded in proving that this led to definite changes in enzyme formation.

Why is one gene

The phrase "one gene, one protein" is inaccurate, as shown by the example of haemoglobin: this protein contains prosthetic haem groups which are not made by the activity of any gene, therefore genes alone cannot make every protein.

When was the gene discovered?

Wilhelm Roux in 1883 speculated that chromosomes are the carriers of inheritance. Danish botanist Wilhelm Johannsen coined the word "gene" ("gen" in Danish and German) in 1909 to describe these fundamental physical and functional units of heredity. William Bateson in 1905 coined the term genetics from the word gene.

How did the first gene form?

One theory biochemists like is called the “RNA World hypothesis.” It focuses on how the first gene made of RNA – DNA's cousin – originated from individual molecules. If Earth spontaneously generated life, then the first biological molecule must have arisen, well, spontaneously, from chemical activity.
