Txhais lus (biology)

  • Kev pib: Lub ribosome sib sau ua ke ib ncig ntawm lub hom phiaj mRNA. Thawj tRNA txuas rau ntawm qhov pib codon.
  • Elongation: Lub tRNA hloov cov amino acid mus rau tRNA sib raug rau cov codon tom ntej.
  • Kev Txiav Txim: Thaum peptidyl tRNA ntsib qhov nres codon, ces lub ribosome folds cov polypeptide rau hauv nws cov qauv kawg.

Yog li ntawd, cov kauj ruam ntawm kev txhais lus yog dab tsi?

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 dua: 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.

Kuj Paub, dab tsi yog cov kauj ruam ntawm kev txhais lus thiab cov protein synthesis? Cov theem ntawm kev txhais lus hauv Protein Synthesis

  • Pib: Ribosomal subunits khi rau mRNA.
  • Elongation: Lub ribosome txav raws mRNA molecule txuas cov amino acids thiab tsim cov saw hlau polypeptide.
  • Kev Txiav Txim: Lub ribosome ncav cuag qhov nres codon, uas txiav cov protein synthesis thiab tso tawm ribosome.

Ua raws li qhov no, ua li cas 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 ib daim ntawv cog lus hu ua ib peptide daim ntawv cog lus.

Vim li cas tus txheej txheem ntawm kev txhais lus tseem ceeb?

Kev txhais lus yog heev tseem ceeb hauv txheej txheem ua cov protein. Tsis muaj transcription thiab txhais lus , koj lub cev yuav tsis muaj peev xwm ua tau cov proteins, lossis ua haujlwm. Proteins tso cai rau koj lub cev ua txhua yam.
