Tsis tiav digestion yog ib qho teeb meem nquag ntsib thaum siv txwv endonucleases. Kev zom zaub mov tsis tiav muaj tshwm sim thaum ntau dhau los yog tsawg dhau enzyme yog siv. Muaj cov kab mob paug hauv cov qauv DNA tau inhibit cov enzymes, kuj ua rau kev zom zaub mov tsis tiav.
Ntxiv rau qhov no, qhov tsis tiav digestion txhais li cas?
Ib digestive tsis tiav lub kaw lus tsuas muaj ib qho qhib. Cov khoom noj mus rau qhov qhib tib yam uas cov khib nyiab tawm. Nws yuav ua zoo li koj lub qhov quav yog qhib tib yam li koj lub qhov ncauj! Lawv tsis muaj qhov zoo nkauj plab system lossis lwm yam kabmob uas peb muaj.
Ib tus kuj tseem yuav nug, vim li cas kuv qhov kev txwv txwv tsis ua haujlwm? Tsis tiav los tsis muaj kev zom zaub mov vim kev ua haujlwm enzyme thaiv los ntawm DNA methylation. Yog tias koj cov enzyme ua haujlwm thiab digests cov tswj DNA thiab tus cov tshuaj tiv thaiv yog teeb tsa siv cov kev mob zoo, tab sis koj tseem pom teeb meem nrog kev zom zaub mov , nws yuav yog vim tus enzyme yog inhibited los ntawm methylation ntawm tus qauv DNA.
Hais txog qhov no, lub hom phiaj ntawm kev txwv digest yog dab tsi?
A txwv digest yog txheej txheem siv hauv kev tshawb fawb txog molecular los npaj DNA rau kev tshuaj xyuas lossis lwm yam kev ua. Cov no cov enzymes hu ua txwv endonucleases lub txwv enzymes , thiab lawv muaj peev xwm cleave DNA molecules ntawm txoj hauj lwm ntawm qhov tshwj xeeb luv luv sequences ntawm lub hauv paus tam sim no.
Yuav ua li cas txwv kev zom cov zom zaub mov kom zoo dua?
Siv tsis pub ntau tshaj qhov pom zoo enzyme tus nqi (piv txwv li, 10 units ntawm enzyme ib microgram ntawm DNA). Txo tus nqi ntawm enzyme hauv cov tshuaj tiv thaiv, yog tias tsim nyog. Zam kev ua kom ntev ntev ntawm kev zom zaub mov cov tshuaj tiv thaiv Siv cov tshuaj tiv thaiv tsis zoo.

Puas yog cov zaub mov organic zoo dua rau koj dua li cov zaub mov hloov pauv?
Feem ntau pom muaj nyob hauv cov qoob loo xws li taum pauv, pob kws thiab canola, GMOs tau tsim los muab cov zaub mov muaj txiaj ntsig zoo rau zaub mov, ntxiv rau tiv thaiv cov qoob loo tiv thaiv kab tsuag. Organic zaub mov, ntawm qhov tod tes, tsis muaj tshuaj tua kab, chiv, kuab tshuaj los yog additives
Yuav muaj dab tsi tshwm sim thaum lub tuam txhab poob mus rau kev ua tsis tiav?
Thaum lub tuam txhab nkag mus rau hauv kev ua kom tiav nws cov cuab tam raug muag kom them rov qab cov neeg qiv nyiaj, lub lag luam kaw, thiab nws lub npe raug tshem tawm ntawm cov npe ntawm Tuam Tsev Tsev. Qhov no yog hu ua Members 'Voluntary Liquidation (MVL). Kev lag luam tsis txaus ntseeg tshwm sim thaum lub tuam txhab tsis tuaj yeem nqa mus rau qhov laj thawj nyiaj txiag
Thaum kev lag luam nkag mus rau kev lag luam vim kev poob qis hauv kev thov dab tsi yuav tshwm sim rau qib nqi?
A) Thaum kev lag luam nkag mus rau kev lag luam poob qis vim qhov kev thov poob qis, yuav ua li cas rau qib nqi? Cov khoom tso tawm thiab cov nqi nkag ib txwm poob thaum muaj kev lag luam poob qis. Tus nqi nce nqi nce thaum lub sij hawm boom thiab ntog thaum lub sij hawm kev lag luam, nws ib txwm tsis mus qis dua xoom vim tias cov nyiaj tau nce tsis tu ncua
Txoj cai zaub mov twg tau dhau los hauv xyoo 1996 thiab hloov pauv cov tshuaj tua kab nyob rau hauv cov zaub mov tau tswj hwm li cas hauv Asmeskas?
Thaum Lub Yim Hli 1996, Thawj Tswj Hwm Clinton tau kos npe rau hauv tsab cai lij choj Food Quality Protection Act (FQPA) [16]. Txoj cai tshiab tau hloov kho Tsoom Fwv Teb Chaws Kab Kab, Fungicide, thiab Rodenticide Act (FIFRA) thiab Txoj Cai Khoom Noj, Tshuaj, thiab Tshuaj pleev ib ce (FDCA), hloov pauv txoj hauv kev EPA tswj cov tshuaj tua kab
Puas yog qhov tseem ceeb uas cov neeg ua zaub mov raug cob qhia kom paub cov khoom xyaw zaub mov vim?
Nws yog ib qho tseem ceeb uas cov neeg ua zaub mov raug cob qhia kom paub cov khoom xyaw zaub mov vim: Lawv yuav tsum tau pab cov neeg muas zaub uas muaj kev fab zaub mov. Cov txheej txheem khaws cia dab tsi cuam tshuam nrog cov khoom noj cua sov kom sov me ntsis thiab tom qab ntawd txias tam sim ntawd?
