Cells txiav txim siab mRNAs los ntawm nyeem lawv cov nucleotides hauv pawg ntawm peb, hu ua codons. Nov yog qee qhov nta ntawm codons: Feem ntau cov codons qhia txog cov amino acid. Peb "stop" codons cim qhov kawg ntawm cov protein.

mRNA coj cov lus nyob qhov twg?

hom RNA uas muaj cov ntaub ntawv tsim cov protein hu ua messenger RNA (mRNA) vim nws nqa cov ntaub ntawv, lossis cov lus, los ntawm DNA tawm ntawm lub nucleus mus rau lub cytoplasm. Kev txhais lus, theem thib ob ntawm kev tau txais los ntawm cov noob mus rau cov protein, tshwm sim hauv cytoplasm.

Dab tsi txiav txim siab rau mRNA code?

Qhov kev txiav txim no yog txiav txim siab los ntawm kev nyiam ntawm codon, ib ntu ntawm peb nucleotides ntawm mRNA, thiab ib qho ntxiv nucleotide triplet ntawm tRNA, hu ua anticodon. Qhov no anticodon kuj qhia txog cov amino acid tshwj xeeb uas tRNA nqa.

Dab tsi txiav txim siab mRNA hauv kev txhais lus?

Txhua tus txheej txheem hu ua gene expression. Hauv kev txhais lus, tus xa xov RNA (mRNA) tau txiav txim siab hauv a ribosome, sab nraum lub nucleus, los tsim cov amino acid tshwj xeeb, lossis polypeptide. … Lub ribosome pab txhawb kev txiav txim siab los ntawm kev ua kom muaj kev sib txuas ntawm tRNA anticodon ua ntu zus rau mRNA codons.

Dab tsi yog cov lus txiav txim tom qab txhais cov kab ke mRNA?

Taw qhia. Cov txheej txheem ntawm kev txhais lus hauv biologyyog qhov kev txiav txim siab ntawm mRNA lus rau hauv cov khoom lag luam polypeptide. Muab lwm txoj hauv kev, cov lus sau ua lus tshuaj ntawm nucleotides yog "txhais" rau hauv cov lus tshuaj ntawm cov amino acids.
