Kev txhais lus : Pib, nruab nrab, thiab xaus

Kev txhais lus muaj ntau yam zoo tib yam peb ntu, tab sis lawv muaj lub npe zoo: pib, elongation, thiab xaus. Initiation ("pib"): nyob rau theem no, lub ribosome tau ua ke nrog mRNA thiab thawj tRNA thiaj li txhais lus tuaj yeem pib

Ib yam li ntawd, 5 kauj ruam ntawm kev sau ntawv yog dab tsi?

RNA tom qab ntawd nkag mus rau kev txhais lus los ua cov protein. Cov kauj ruam tseem ceeb ntawm kev sau ntawv yog pib , txhawb kev tshem tawm, elongation , thiab kev txiav txim.

Tsis tas li ntawd, cov kauj ruam ntawm kev txhais lus hauv eukaryotes yog dab tsi? Eukaryotic txhais lus yog cov txheej txheem lom neeg uas tus tub txib RNA tau muab txhais ua cov protein hauv eukaryotes. Nws muaj plaub theem: pib , elongation, termination, thiab recycling.

Yog li ntawd, dab tsi tshwm sim hauv txhua theem ntawm kev txhais lus?

Kev txhais lus mRNA molecule los ntawm ribosome tshwm sim hauv peb theem : pib, elongation, thiab termination. Thaum lub sij hawm elongation theem , lub ribosome tseem txhais txhua codon nyob rau hauv lem. Txhua Cov amino acid sib raug tau ntxiv rau cov saw loj hlob thiab txuas ntawm a daim ntawv cog lus hu ua a peptide daim ntawv cog lus.

Tus txheej txheem ntawm kev txhais lus yog dab tsi?

Kev txhais lus yog cov txheej txheem ntawm kev txhais lus qhov sib lawv liag ntawm tus tub txib RNA (mRNA) molecule rau ib theem ntawm cov amino acids thaum lub sij hawm cov protein synthesis. Cov noob caj noob ces piav qhia txog kev sib raug zoo ntawm qhov sib lawv liag ntawm lub hauv paus khub hauv ib lub noob thiab cov amino acid sib txuas uas nws encodes.
