Yog vim li cas Lambda DNA feem ntau yog siv yog vim hais tias qhov luaj li cas ntawm cov fragments generated los ntawm ib tug xov tooj ntawm kev txwv enzymes, raws li zoo raws li Hind III, yog zoo cwj pwm kom ib tug calibr Tab sis. Lambda DNA tsis yog tus xwb DNA uas tau siv raws li qhov loj me tus cim.

Kuj nug, vim li cas lambda DNA siv?

Lambda DNA (48, 502 bp) kuj siv Raws li qhov ntsuas qhov hnyav molecular thaum lub sij hawm nucleic acid gel tsom xam tom qab kev zom zaub mov nrog kev txwv enzyme (xws li HindIII). Lambda DNA tuaj yeem yog siv raws li ib tug substrate nyob rau hauv txwv enzyme kev soj ntsuam.

Tom qab ntawd, lo lus nug yog, vim li cas cov kws tshawb fawb yeej ib txwm khiav txoj kab cim? Yog vim li cas a tus cim siv thaum khiav cov tawg ntawm cov gel? A tus cim muaj cov DNA seem uas paub qhov loj. Cov cim yog khiav nyob rau hauv txhua txhua gel rau kev sib piv nrog cov tsis paub tawg paj nyob rau hauv lwm yam gel txoj kab.

Tom qab, lo lus nug yog, dab tsi yog lambda phage DNA?

Enterobacteria phage λ ( lambda pab , coliphage λ, officially Escherichia virus Lambda ) yog kab mob kab mob, los yog kab mob bacteriophage , uas kis tau cov kab mob Escherichia coli (E. Lub taub hau muaj cov phage ua ob-strand linear DNA genome. Thaum kis kab mob, cov phage particle paub thiab khi rau nws tus tswv tsev, E.

Muaj pes tsawg feem HindIII yuav txiav lambda DNA rau hauv?
