Cov no txiv hmab txiv ntoo tau xaiv vim lawv yog cov txiv tsawb (txiv tsawb) 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.

Hais txog qhov no, lub hom phiaj ntawm mashing txiv tsawb hauv DNA extraction yog dab tsi?

Mashing txiv tsawb exposes ib tug ntau dua deg cheeb tsam ntawm uas rho tawm tus DNA . Cov kua xab npum yog ntxiv los pab ua kom cov cell membranes tso tawm DNA . Cov kauj ruam pom (pob qhov sib tov los ntawm cov strainer) tso cai rau kev sau cov DNA thiab lwm yam cellulars.

Ib tug kuj yuav nug, cov txiv hmab txiv ntoo twg yog qhov zoo tshaj plaws rau kev rho tawm DNA? Kev sim ua kom huv DNA los ntawm txiv hmab txiv ntoo Txiv tsawb, kiwis thiab strawberries txhua yam ua haujlwm zoo.

Ua raws li qhov no hauv kev txiav txim siab, vim li cas nws thiaj li yuav tsum tau muab cov txiv pos nphuab hauv DNA rho tawm?

Txhawm rau rhuav tshem cov phab ntsa ntawm tes, cellular thiab nuclear membranes. Cov rho tawm tsis pab kom tso tawm DNA los ntawm ib puag ncig cell Cheebtsam ntawm crushed strawberry.

Lub hom phiaj ntawm DNA rho tawm yog dab tsi?

Muaj peev xwm extract DNA yog qhov tseem ceeb tshaj plaws rau kev kawm txog caj ces ntawm tus kab mob thiab rau kev txhim kho ntawm kev kuaj mob thiab tshuaj. Nws tseem yog ib qho tseem ceeb rau kev ua cov kev tshawb fawb forensic, sequencing genomes, ntes cov kab mob thiab cov kab mob hauv ib puag ncig thiab rau kev txiav txim siab txiv neej.
