Kev piav qhia: Cov enzymes xws li txwv tsis pub cov enzymes yuav tsum paub txog cov kab ke tshwj xeeb txhawm rau ua nws txoj haujlwm. Nws khi rau DNA nkaus xwb hauv ib qho kev teeb tsa tshwj xeeb. … Ib kab lus palindromic kuj nce txoj hauv kev uas ob leeg DNA raug txiav.

Cov chaw txwv puas tuaj yeem yog palindromes?

Txoj kev txwv-hloov kho yog siv los ua cov txheej txheem tiv thaiv tiv thaiv kev cuam tshuam tsis tsim nyog ntawm DNA txawv teb chaws. Cov kev lees paub ua ntu zus rau hom II txwv tsis pub enzymes thiab lawv cov tshuaj methylases feem ntau yog palindromes.

Puas txwv cov enzymes palindromic?

Ntau qhov kev txwv tsis pub muaj txiaj ntsig zoo tshaj plaws paub txog palindromic DNA sequences thiab raug cais raws li Hom IIP.

Vim li cas kev txwv endonucleases txheeb xyuas thiab tshem tawm cov kab mob palindromic?

Kev txwv enzymes, tseem hu ua kev txwv endonucleases, txiav ob npaug ntawm DNA molecules los ntawm cleaving phosphodiester bonds ntawm palindromic sequences. … Ntau zaus tshaj qhov tsis, qhov kev txiav txim ntawm kev txwv enzyme ua rau ob lub nplaum nplaum uas tuaj yeem pab tau zoo hauv kev tsim cov DNA molecules recombinant.

txhais li cas los ntawm palindromic sequence?

Ib kab lus palindromic yog a nucleic acid ua ntu zus nyob rau hauv ob-stranded DNA lossis RNA molecule nyob rau hauv kev nyeem ntawv nyob rau hauv ib qho kev taw qhia (piv txwv li 5 ' txog 3') ntawm ib txoj hlua khi sib txuas ua ntu nyeem hauv opposite direction(piv txwv li 3' txog 5') ntawm qhov sib ntxiv strand.
