Qhov laj thawj yog vim li cas introns tsis suav tias yog thaj chaw tsis tau txhaisyog tias cov introns tau sib cais tawm hauv cov txheej txheem ntawm RNA splicing. Cov introns tsis suav nrog hauv mRNA molecule paub tab uas yuav raug kev txhais lus thiab yog li suav hais tias tsis yog-protein-coding RNA.
Dab tsi yog thaj chaw uas tsis tau txhais lus ntawm cov noob?
5′ cheeb tsam uas tsis tau txhais lus (UTR) yog thaj chaw tswj hwm ntawm DNA nyob ntawm 5′ kawg ntawm tag nrho cov protein-coding noob uas tau hloov mus rau hauv mRNA tab sis tsis txhais ua cov protein.
Dab tsi yog qhov txawv ntawm thaj chaw uas tsis tau txhais lus thiab introns?
Qhov sib txawv tseem ceeb ntawm UTR thiab intron yog UTR yog qhov tsis yog-coding nucleotide ib ntus uas suav nrog hauv mRNA kab ke paub tabthaum intron yog ib ntu uas tsis suav nrog mRNA molecule uas paub tab. … Nyob rau hauv sib piv, ib qho intron yog ib tug tsis-coding sequence uas pom nyob rau hauv nruab nrab ntawm exons ntawm cov noob.
Puas yog thaj tsam tswj hwm?
Ntau lwm cov kev tshawb fawb tau txheeb xyuas qhov tshwj xeeb intron-hosted DNA cov ntsiab lus uas tswj kev pib sau ntawv. … Qhov lees txais kev txhais lus ntawm qhov kev tshawb pom no yog tias cov introns no ntev dua vim tias lawv nyob ntau dua cis tswj hwm ib ntus, yuav muaj feem cuam tshuam nrog kev pib sau.
Puas yog cov cheeb tsam uas tsis tau txhais lus exons?
Hauv cov noob caj noob ces protein, cov exons suav nrog ob qho tib si protein-coding sequence thiab 5′- thiab 3′-untranslated cheeb tsam (UTR). … Qee qhov tsis-coding RNACov ntawv sau tseg kuj muaj exons thiab introns.
