James Watson

James D. Watson.

Source: National Machadyada Caafimaadka Sannadkii 1951-kii, Watson waxa uu aaday Cambridge, England si uu uga shaqeeyo Shaybaadhka Cavendish si uu u darso qaabka DNA-da. Halkaa waxa uu kula kulmay saynisyahan kale oo la odhan jiray Francis Crick. Watson iyo Crick waxay ogaadeen inay isku dan leeyihiin. Waxay bilaabeen inay wada shaqeeyaan. Sannadkii 1953-kii waxay daabaceen qaab-dhismeedka unugga DNA-ga. Helitaankani waxa uu noqday mid ka mid ah cilmi-baadhistii ugu muhiimsanayd ee qarnigii 20-aad

Watson (oo ay weheliyaan Francis Crick, Rosalind Franklin,iyo Maurice Wilkins) waxaa la siiyay abaalmarinta Nobel Prize ee Physiology ama Medicine 1962 si loo helo qaabka DNA-da. Waxa uu sii watay cilmi-baadhistiisa ku saabsan hidde-sidaha oo qoray buugaag badan iyo sidoo kale buugga ugu iibka badan The Double Helix kaas oo soo taxnaa daah-furkii caanka ahaa.

Watson ka dib waxa uu agaasime ka noqday Cold Spring Harbor Lab ee New York. halkaas oo uu hormuud ka ahaa cilmi-baadhistii ugu horreysay ee kansarka. Waxa kale oo uu gacan ka gaystay samaynta mashruuca Human Genome kaas oo khariidadeeyay habka hidde-sidaha aadanaha.

Francis Crick

Francis Crick waxa uu ku dhashay Weston Favell, England bishii June 8, 1916. Aabihii wuxuu ahaa kabo-sameeyaha, laakiin Francis wuxuu markiiba helay jacaylka waxbarashada iyo sayniska. Waxbarashadiisa si wanaagsan ayuu uga soo baxay oo uu ka galay Jaamacadda London University College. Crick wuxuu ku guuleystay dhowr abaalmarino cilmi-baaris markii uu la kulmay James Watson Shaybaadhka Cavendish ee Cambridge, England. Isla markiiba waxay sameeyeen daah-furkoodii caanka ahaa ee DNA-da double helix sanadkii 1953.

Kadib markii ay sameeyeen daahfurka oo ay ku guulaysteen abaalmarinta Nobel Prize 1962, Crick waxa uu sii watay cilmi-baadhistiisa hidde-sidayaasha ee Cambridge. Ka dib waxa uu sannado badan ka soo shaqeeyay cilmi-baare cilmi-baaris ah Machadka Salk ee California. Crick wuxuu u dhintay kansarka mindhicirka July 28, 2004.

> Baahinta Qaab-dhismeedka DNA-da >

Horraantii 1950-meeyadii, saynisyahannadu waxay wax badan ka barteen hidde-sideyaasha, laakiin wali way sii socdaan. ma fahmin qaab dhismeedka molecule DNA-ga.Saynis yahanadu waxay u baahdeen inay fahmaan qaab dhismeedka DNA-da si ay si buuxda u fahmaan genetics. Shaybaadhka Cavendish wuxuu isu keenay koox si ay isku dayaan oo ay u xaliyaan dhibaatada ka hor intaysan koox Maraykan ah oo uu hoggaaminayo biochemist caan ah Linus Pauling awoodin. Waxay noqotay tartan lagu ogaanayo cidda marka hore ogaan karta!

Markii Crick iyo Watson ay ku kulmeen Cambridge waxay si dhakhso ah u ogaadeen in ay isku mid yihiin xamaasadda xallinta qaabka DNA-ga. Labaduba waxay lahaayeen fikrado isku mid ah iyo sidoo kale sida dhibaatada loo xalin karo. Inkasta oo ay lahaayeen shakhsiyaad aad u kala duwan, waxay noqdeen saaxiibo wanaagsan oo midba midka kale ixtiraamo shaqadiisa.

Isku daygii ugu horreeyay ee 1951-kii wuu fashilmay, laakiin way ku sii adkaysteen. Waxay kaloo isticmaaleen macluumaadka sawirada raajada si ay fikrado uga siiyaan qaabdhismeedka. Rosalind Franklin iyo Maurice Wilkins waxay ahaayeen laba saynis yahan oo khabiir ku ahaa qaadista sawiradan. Crick iyo Watson waxay awoodeen inay helaan macluumaad qiimo leh iyagoo baranaya sawiro ay qaadeen Franklin iyo Wilkins.

Sannadkii 1953, Crick iyo Watson waxay awoodeen inay isku duba ridaan qaab-dhismeed sax ah oo DNA ah. Qaabku wuxuu isticmaalay qaab qalloocan "helix labajibbaaran". Qaabkan ayaa ka caawin doona saynis yahanada aduunka oo dhan inay wax badan ka bartaangenetics.
