Ib piv txwv ntawm niaj hnub biotechnology yog genetic engineering. Genetic engineering yog tus txheej txheem ntawm kev hloov cov noob caj noob ces ntawm cov kab mob los yog hloov cov noob hauv cov kab mob kom tshem tawm lossis ntxiv qhov xav tau lossis tus yam ntxwv. Piv txwv ntawm genetic engineering tau piav qhia tom qab hauv daim ntawv no.
Tom qab ntawd, dab tsi yog qee qhov piv txwv ntawm niaj hnub biotechnology?
Cov kev siv tseem ceeb ntawm biotechnology suav nrog:
- DNA profileing - yog xav paub ntxiv mus saib kab lus DNA profileing.
- DNA cloning - yog xav paub ntxiv mus saib kab lus DNA cloning.
- transgenesis.
- genome tsom xam.
- stem cells thiab cov ntaub so ntswg engineering - rau cov ntaub ntawv ntxiv mus saib kab lus Stem cells.
Ib sab saum toj no, dab tsi yog qhov niaj hnub biotechnology? Niaj hnub nimno biotechnology yog ib lo lus uas tau txais los ntawm lub rooj sib tham thoob ntiaj teb kom xa mus biotechnological Cov tswv yim rau kev tswj hwm cov khoom siv caj ces thiab kev sib xyaw ntawm cov hlwb tshaj li cov kev txwv tsis pub yug me nyuam thiab nws kuj yog hais txog kev hloov kho thiab kev tswj hwm cov kab mob nyob thiab cov organic teeb meem [18-19].
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog kev siv biotechnology tam sim no?
Biotechnology muaj cov ntawv thov hauv plaub qhov loj kev lag luam thaj chaw, suav nrog kev kho mob (kev kho mob), qoob loo ntau lawm thiab kev ua liaj ua teb , tsis yog khoom noj ( kev lag luam ) siv cov qoob loo thiab lwm yam khoom (xws li biodegradable plastics, zaub roj, biofuels), thiab kev siv ib puag ncig.
Dab tsi yog qhov txawv ntawm niaj hnub thiab tsoos biotechnology?
Peb ua tau paub qhov txawv ntawm ib txwm thiab niaj hnub biotechnology . Ib txwm biotechnology yog hais txog txoj kev qub uas siv cov kab mob muaj sia los ua cov khoom tshiab lossis hloov cov khoom uas twb muaj lawm. Nrog niaj hnub biotechnology peb tsis tsuas yog ua lub cev manipulation ntawm qhov muag pom tab sis kuj nyob rau theem molecular.

Dab tsi yog qhov piv txwv piv txwv hauv kev txheeb cais?
Nyob rau hauv kev txheeb cais, sampling bias yog ib tug bias nyob rau hauv uas ib tug piv txwv yog sau nyob rau hauv xws li ib tug txoj kev uas ib co tswv cuab ntawm cov neeg npaj muaj ib tug tsawg sampling probability tshaj lwm tus
Qhov kev hloov pauv twg yog qhov piv txwv ntawm kev tswj kom muaj kev sib npaug sib npaug?
2 Qhov kev hloov pauv twg yog qhov piv txwv ntawm kev tswj hwm qhov sib npaug ntawm qhov sib npaug? (1) Ib tsob nroj wilts thaum dej ntau los ntawm nplooj ntau dua li ploj los ntawm cov hauv paus hniav. (2) Ib tsob nroj hloov daj thaum lub teeb theem qis heev. (3) Insulin tso tawm thaum cov piam thaj hauv cov ntshav siab
Qhov kev siv nyiaj txiag siv nyiaj txiag twg muab txhais tau tias los sib piv cov nqi ntawm cov khoom thiab cov kev pabcuam?
Ntau qhov chaw ntawm lub ntiaj teb tseem siv kev sib pauv tab sis raws li kev lag luam ua lag luam tshwj xeeb, nws nyuaj dhau los tsim kom muaj txiaj ntsig ntawm cov khoom sib txawv. Nyiaj, yog li ntawd, ua kev sib pauv yooj yim dua. - Nws kuj muab ib txoj hauv kev los sib piv cov nqi ntawm cov khoom thiab cov kev pabcuam
Hnub twg ntawm tsab ntawv sawv cev tswj hwm yuav tsum yog hnub twg?
Kev sawv cev ntawm kev tswj hwm yog ib tsab ntawv muab los ntawm tus neeg siv khoom rau tus neeg sau ntawv sau ua ib feem ntawm cov ntaub ntawv pov thawj. Tsab ntawv sawv cev yuav tsum them rau txhua lub sijhawm uas suav nrog hauv daim ntawv tshaj tawm kev tshuaj xyuas, thiab yuav tsum tau sau hnub tim tib hnub ntawm kev tshawb xyuas ua tiav
Qhov twg yog ib qho piv txwv ntawm cov neeg siv khoom thawj qib lossis thawj tus neeg siv khoom?
Cov neeg siv khoom tseem ceeb cuam tshuam nrog cov neeg tsim khoom thiab cov neeg siv khoom thib ob. Lawv tuaj yeem cuam tshuam nrog cov decomposers, txawm tias feem ntau lawv yuav cuam tshuam nrog cov neeg tsim khoom / cov neeg siv khoom thib ob. Kab laum paj rwb, nas teb, kab nyom, thiab tus ntoo ntsaum yog tag nrho cov piv txwv ntawm cov neeg siv khoom thawj qib
