Donald D. Brown

Donald David Brown (30 Disemba 1931 - 31 Mee 2023) ko biyolojiyanke Amerik e gooto e ardiiɓe ɓalli molekula.

 Ɓiɗɗo 
Brown jibini nder Cincinnati, Ohio, to Dr. Albert Brown, doktoor gite, e Louise Rauh.

 Jaŋde 
Brown yahdi Dartmouth College. E hitaande 1956, o heɓii doktoor e doktoor e nder jaŋde Chicago Medical School, o winndi deftere maako dow kuugal virus.

Caggal nde o waɗi hitaande e nder suudu charity ha New Orleans, Brown fuɗɗi wonde duuɓi ɗiɗi e National Institutes of Health e hooreejo neuroscientist Seymour Kety. E hitaande 1959, o waɗi janngude ɓaawo doktoor e Jacques Monod e nder suudu Pasteur to Paris, Farayse.

Brown hawti e Carnegie Institution nder Baltimore, Maryland nder hitaande 1961. O fuɗɗii jokkude to Daartol Embryology bana anndal ngal.  Nder 1976, o laati mawɗo jaayɗe. Fuɗɗugo nder 1969, o laati jannginoowo jaayndiyaaku e jaayndiyankeeɓe e Johns Hopkins. O wonnoo darnde Ameriknaaɓe Academy of Arts and Sciences, National Academy of Sciences, e American Philosophical Society.

Brown jaɓɓii nder Carnegie Institution e nder hitaande 2005.

 Fuuɓol 
Brown e John Gurdon tawi footi footi foodi footi e nucleoli nden e non ɓe maaki ribosomal RNAs (rRNAs), ko holli nucleoli woni nokkuure footi e rRNA. Ɓaawo, Brown e Igor Dawid ɗon ɗaɓɓita daliila ngam ɗume eggugo be'e woodi nucleoli ɗuuɗugo diga ɓesngu ɓesngu. Ɓe holli wonde limgal gene rDNA ɓeydaniama wakkati oogenesis ngam wallugo ribosome ɗi ngam egguki go'o (ngam anndal waɗi Joseph Gall e hoore mum). Caggal nde Max Birnstiel heɓii yahude gene rDNA, Brown woni arandeejo mo laaɓini geneeji ɗi ɗon ɓeyda gene 5S rRNA nden heɓii laawol haɓɓugo ɗe in vitro. Ko goonga, 5S rRNA gene'en laati eukaryotic genes arandeeji ɗi ɓe ɓeydi. Brown e Robert Roeder tawi ɓaawo ɗun, ko jaɓɓol jeenuuji ɗi ɗon jeewta e jaɓɓol jaɓɓol ( (FIIIA) ) je je ɗon haɓɓoo nder gene.
