Kinetin yog thawj zaug cais los ntawm Miller thiab Skoog et al. ua cov khoom sib xyaw los ntawm autoclaved herring phev DNA uas muaj kev faib tawm ntawm tes. Nws tau muab lub npe kinetin vim nws muaj peev xwm ua kom muaj kev sib faib ntawm tes, yog tias auxin nyob hauv nruab nrab.
Leej twg nrhiav tau kinetin?
Cytokinins tau tshawb pom los ntawm F Skoog, C Miller, thiab cov neeg ua haujlwm sib koom ua ke thaum xyoo 1950 yog yam uas txhawb kev faib cell (cytokinesis). Thawj cytokinin pom yog ib qho adenine (aminopurine) derivative hu ua 'kinetin' (6-furfuryl aminopurine), uas tau raug cais tawm ua cov khoom lag luam DNA degradation.
Leej twg txheeb xyuas Crystaletized kinetin ua ntej?
4.1 Taw qhia. Kwv yees li 50 xyoo dhau los, cov tshuaj lom neeg uas txhawb nqa kev loj hlob ntawm tes hauv cov kab lis kev cai luam yeeb yog thawj zaug purified thiab crystallized los ntawm Skoog thiab nws cov neeg koom tes los ntawm autoclaved herring phev DNA extracts.
Yog nrhiav tau los ntawm Skoog Miller li al?
Cytokinins yog ib pawg sib txawv ntawm N6-substituted purine derivatives muaj peev xwm inducing cog cell faib. Qhov kev tshawb pom ntawm cytokinins los ntawm Folke Skoog thiab cov npoj yaig hauv xyoo 1950 tau pib tsom mus rau kinetin, cov khoom sib xyaw ua ke tau los ntawm autoclaved salmon phev DNA (Miller et al., 1955).
Kinetin Chav Kawm 11 yog dab tsi?
Kinetin yog cov khoom siv hauv cell faib hauv cov nroj tsuag thiab zoo ib yam li kinin. Nws yog cov tshuaj hormones cog uas pab hauv kev faib cov cell. Cov lus teb tiav: Kinetin yog a cytokinin uas pab cov nroj tsuag kom loj hlob.

Leej twg coined lo lus viroid?
Nyob rau xyoo 1971 Theodor O. Diener tau qhia tias tus neeg sawv cev tsis yog tus kab mob, tab sis yog hom kab mob tshiab uas xav tsis thoob, 1/80 ntawm qhov loj ntawm cov kab mob, uas nws hais lo lus "viroid" . Leej twg pom tus kab mob viroids xyoo twg?
Leej twg coined lo lus sarcode?
Felix Dujardin yog tus kws kho tsiaj hauv Fab Kis. Nws yog qhov tseem ceeb rau nws txoj kev tshawb fawb hauv protozoan. Dujardin tau ua haujlwm nrog cov tsiaj txhu hauv microscopic, thiab xyoo 1834 tau hais tias ib pab pawg tshiab ntawm cov kab mob hu ua Rhizopoda.
Leej twg coined lo lus tsaus zog?
Michael Turner, tus kws tshawb fawb theoretical cosmologist ntawm University of Chicago, tau sau lo lus "dub zog" los piav txog qhov tsis paub ua rau qhov kev nthuav dav no. Yuav luag ob xyoo lawm, physicists tau tsim txoj kev xav txog lub zog tsaus ntuj yuav ua li cas .
Leej twg coined lo lus paleomagnetism?
Kev kawm ntawm paleomagnetism pib hauv 1940s thaum tus kws kho mob Askiv Patrick M.S. Blackett (1897–1974) tau tsim ib lub cuab yeej los ntsuas qhov me me ntawm cov hlau nplaum uas cuam tshuam nrog cov hlau nplaum sib nqus. Lub astatic magnetometer muaj ib tug xov tooj ntawm cov hlau nplaum me me raug tshem tawm ntawm ib qho fiber ntau .
Leej twg coined lo lus socialism?
Marx thiab Engels tau tsim lub cev ntawm cov tswv yim uas lawv hu ua kev tshawb fawb kev lag luam, feem ntau hu ua Marxism. Marxism suav nrog txoj kev xav ntawm keeb kwm (keeb kwm materialism) nrog rau kev nom kev tswv, kev lag luam thiab kev xav txog kev xav philosophical theory Kant's political philosophy tau piav raws li liberal rau nws qhov kev xav txog kev txwv ntawm lub xeev raws li kev cog lus ntawm kev sib raug zoo li ib qho kev cai.
