Txheej txheem. Lub hom phiaj ntawm mashing up lub strawberry yog los rhuav tshem cov phab ntsa ntawm tes nrog rau cov cellular thiab nuclear membranes. Cov rho tawm tsis pub pab tso tawm DNA los ntawm ib puag ncig cell Cheebtsam ntawm crushed strawberry . Cov lim tau siv los tshem tawm cov khoom loj ntawm cov tshuaj xws li cov noob.
Tsis tas li ntawd, vim li cas strawberries siv hauv DNA extraction?
Ripe strawberries yog qhov zoo tshaj plaws rau extracting DNA vim tias lawv yooj yim rau pulverize thiab muaj cov enzymes hu ua pectinases thiab cellulases uas pab ua kom cov phab ntsa ntawm tes. Thiab qhov tseem ceeb tshaj plaws, strawberries muaj yim daim ntawv luam ntawm txhua tus chromosome (lawv yog octoploid), yog li muaj ntau DNA cais.
Qhov thib ob, vim li cas peb ntxiv cov tshuaj ntxuav tes rau strawberries? Ntxiv detergent los yog xab npum rhuav tshem cov cell membranes, tso cov DNA. Cog hlwb, tab sis tsis yog tsiaj hlwb, kuj muaj cov phab ntsa txhav nyob ib ncig ntawm sab nraud ntawm tes. Cov tub ntxhais kawm yuav tsum smash lub strawberry nyob rau hauv lub hnab kom tawg cov phab ntsa ntawm tes thiab nthuav tawm cov membranes hauv cov xab npum los yog tshuaj ntxuav tes.
Ntxiv rau qhov no, vim li cas peb thiaj li yuav tsum tau mash cov txiv hmab txiv ntoo hauv kev cais DNA?
Cov no txiv hmab txiv ntoo tau xaiv vim lawv yog triploid (bananas) thiab octoploid (strawberries). Qhov no txhais tau tias lawv muaj ntau heev DNA sab hauv ntawm lawv cov hlwb, uas txhais tau hais tias muaj ntau ntau rau peb rho tawm . Lub hom phiaj ntawm mashing yog rhuav tshem cov phab ntsa ntawm tes.
Lub hom phiaj ntawm kev rho tawm DNA yog dab tsi?
Muaj peev xwm extract DNA Nws yog ib qho tseem ceeb rau kev kawm txog cov caj ces ntawm tus kab mob thiab kev txhim kho ntawm kev kuaj mob thiab tshuaj. Nws tseem yog ib qho tseem ceeb rau kev tshawb fawb forensic, sequencing genomes, kuaj cov kab mob thiab cov kab mob hauv ib puag ncig thiab txiav txim siab txiv neej.

Vim li cas peb yuav tsum tau mash txiv hmab txiv ntoo hauv kev cais DNA?
Cov txiv hmab txiv ntoo no tau raug xaiv vim lawv yogtriploid (bananas) thiab octoploid (strawberries). Qhov no txhais tau hais tias lawv muaj ntau DNA hauv lawv lub hlwb, uas txhais tau hais tias muaj ntau ntau rau peb rho tawm. Lub hom phiaj ntawm themashing yog los rhuav tshem cov phab ntsa ntawm tes
Cov txiv pos nphuab puas muaj DNA?
Cov txiv pos nphuab yog qhov zoo tshaj plaws rau kev rho tawm DNA vim tias lawv yooj yim rau pulverize thiab muaj cov enzymes hu ua pectinases thiab cellulases uas pab ua kom cov phab ntsa ntawm tes. Thiab qhov tseem ceeb tshaj plaws, txiv pos nphuab muaj yim daim ntawv ntawm txhua tus chromosome (lawv yog octoploid), yog li muaj ntau DNA los cais tawm
Vim li cas Thomas Hunt Morgan siv cov txiv hmab txiv ntoo yoov rau nws cov kev sim caj ces?
Thomas Hunt Morgan, uas kawm cov txiv hmab txiv ntoo yoov, muab thawj qhov kev pom zoo ntawm chromosome txoj kev xav. Morgan pom qhov kev hloov pauv uas cuam tshuam rau lub qhov muag xim. Nws tau pom tias kev hloov pauv tau sib txawv los ntawm txiv neej thiab poj niam yoov
Vim li cas koj thiaj li yuav tsum tau siv lub hauv paus ntsiab lus los saib cov Substages ntawm mitosis?
Cov lus qhia hauv paus dos feem ntau siv los kawm txog mitosis. Lawv yog cov chaw ntawm kev loj hlob sai, yog li cov hlwb tau faib sai
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
