Ilimi da farkon rayuwa[gyara sashe | gyara masomin]

An haifi Brenner a garin Germiston a Transvaal a lokacin (yau a Gauteng ), Afirka ta Kudu, a ranar 13 ga Janairu 1927. Iyayensa, Leah (née Blecher) da Morris Brenner, baƙi ne na Yahudawa . Mahaifinsa, ma'aikacin cobbler, ya zo Afirka ta Kudu daga Lithuania a cikin 1910, da mahaifiyarsa daga Riga, Latvia, a 1922. Yana da 'yar'uwa ɗaya, Phyllis.

A cikin 1946 Wilfred Le Gros Clark ya gayyaci Brenner zuwa Sashensa na Anatomy a Oxford, yayin ziyarar da ya kai Afirka ta Kudu. An shawo kan Brenner ya kammala karatunsa na likitanci maimakon.

Bayan DPhil nasa, Brenner ya yi binciken digiri na biyu a Jami'ar California, Berkeley . Ya shafe shekaru 20 masu zuwa a Laboratory of Molecular Biology a Cambridge. A can, a cikin shekarun 1960, ya ba da gudummawa ga ilimin kwayoyin halitta, sannan filin da ke tasowa. A 1976 ya shiga Cibiyar Salk a California .

Tare da Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, da Beryl M. Oughton, yana ɗaya daga cikin mutanen farko a cikin Afrilu 1953 don ganin samfurin tsarin DNA, wanda Francis Crick da James Watson suka gina; a lokacin shi da sauran masana kimiyya suna aiki a Sashen Chemistry na Jami'ar Oxford . Duk sun gamsu da sabon samfurin DNA, musamman Brenner, wanda daga baya ya yi aiki tare da Crick a cikin dakin gwaje-gwaje na Cavendish a Jami'ar Cambridge da sabuwar Cibiyar Binciken Likitanci (MRC) Laboratory of Molecular Biology (LMB). A cewar Beryl Oughton, daga baya Rimmer, duk sun yi tafiya tare a cikin motoci biyu sau ɗaya Dorothy Hodgkin ta sanar da su cewa sun tafi Cambridge don ganin samfurin tsarin DNA.

Brenner ya ba da gudummawa da yawa na seminal zuwa filin da ke tasowa na ilimin halitta a cikin 1960s (duba rukunin Phage ). Na farko shine tabbatar da cewa duk jeri-nauyen coding na kwayoyin halitta ba zai yiwu ba. Wannan hangen nesa ya raba aikin coding daga ƙayyadaddun tsari kamar yadda aka tsara a cikin lambar wayo ta George Gamow . Wannan ya sa Francis Crick ya ba da shawarar ra'ayi na kwayoyin halitta (daga baya an gano shi azaman canja wurin RNA ko tRNA) wanda ke canza bayanan kwayoyin halitta daga RNA zuwa sunadarai. Brenner ya ba da suna " adaftar hasashe " a cikin 1955. Rabuwar jiki tsakanin anticodon da amino acid akan tRNA shine tushen kwararar bayanai na unidirectional a cikin amintattun tsarin halittu. An fi sanin wannan a matsayin babban akidar ilmin kwayoyin halitta, watau bayanai suna gudana daga acid nucleic zuwa furotin kuma baya taba daga furotin zuwa acid nucleic. Bayan wannan fahimtar adaftan, Brenner ya fahimci manufar manzo RNA yayin tattaunawar Afrilu 1960 tare da Crick da François Yakubu, tare da Yakubu da Matiyu Meselson sun ci gaba da tabbatar da wanzuwarsa daga baya a lokacin bazara. [1] Sa'an nan kuma, tare da Crick, Leslie Barnett, da Richard J. Watts-Tobin, Brenner ya nuna jinsin nau'in nau'in nau'in nau'in fassarar furotin ta hanyar Crick, Brenner, Barnett, Watts-Tobin et al. gwaji na 1961, [2] wanda ya gano maye gurbi na frameshift .
