George Wells Beadle (22 Oktober 1903 – 9 Juni 1989) adalah genetikawan Amerika Serikat yang mempelajari jamur roti merah Neurospora.[1]

Kehidupan

[sunting | sunting sumber]

Beadle menerima gelar sarjana dan magister sains dari University of Nebraska dan gelar Ph.D dari Cornell pada tahun 1931. Ia juga pernah menjadi Profesor Biologi dan kepala divisi Biologi di Cal Tech dari tahun 1947 hingga 1961. Beadle pernah menjadi Presiden pada Genetics Society of America and of the American Association for the Advancement of Science.[1]

Hasil Penelitian

[sunting | sunting sumber]

Mengarahkan sinar X dan UV ke jamur itu, menyebabkannya bermutasi. Mereka menemukan bahwa semua reaksi biokimiawi pada semua makhluk hidup dikontrol secara bertahap oleh gen, yang mana setiap gen mengontrol langkah tertentu pada sebuah reaksi. Maka Beadle menyimpulkan bahwa karakteristik fungsi gen adalah mengendalikan sintesis enzim tertentu. Atas hipotesis ini, yang diterbitkan bersama Edward Lawrie Tatum, ia menerima Hadiah Nobel dalam Kedokteran 1958 bersama Edward Tatum dan Joshua Lederberg.[1]
