Art of Protein Synthesis
Hauv eukaryotic hlwb, kev sau ntawv tshwm sim nyob rau hauv lub nucleus. Thaum kev sau ntawv , DNA yog siv los ua ib qho qauv los ua ib qho molecule ntawm messenger RNA (mRNA). Thaum lub sij hawm txhais lus, cov noob caj noob ces hauv mRNA yog nyeem thiab siv los ua ib qho protein ntau.
Xav txog qhov no, vim li cas qhov kev hloov pauv tseem ceeb rau cov protein synthesis?
Lub hom phiaj ntawm kev sau ntawv yog ua ib daim ntawv theej RNA ntawm cov noob caj noob ces DNA. Rau ib protein ntau -coding gene, daim ntawv theej RNA, lossis cov ntawv sau tseg, nqa cov ntaub ntawv xav tau los tsim cov polypeptide ( protein ntau los yog protein ntau subunit). Eukaryotic cov ntawv sau tseg yuav tsum tau mus dhau qee cov kauj ruam ua ntej kev txhais lus rau hauv cov proteins.
Ib tug kuj yuav nug, dab tsi yog 7 kauj ruam ntawm cov protein synthesis? Xya theem ntawm Protein Synthesis
- Thaum cov cai tau nyeem tag lawm, lub teeb liab nres tau muab thiab cov protein synthesis tiav thiab cov protein mus qhov twg nws xav tau. Qhov no yog Twinkie tiag.
- m RNA muab cov lej theej tawm ntawm cov nucleus mus rau ribosomes. Cov ribosomes "nyeem" theej DNA code. Muag Kickoff - EnergyWSales Kickoff - Ene…
Qhov thib ob, dab tsi yog 5 kauj ruam hauv kev tsim cov protein?
Cov ntsiab lus hauv cov teeb no (5)
- Daim ntawv luam ntawm ib sab ntawm DNA strand yog tsim (hu ua mRNA, messenger RNA)
- mRNA txav mus rau cytoplasm, ces ribosome.
- mRNA mus dhau ribosome 3 lub hauv paus ib zaug.
- Hloov RNA (tRNA) sib tw nrog qhib DNA hauv paus.
- tRNA tso tawm cov amino acid nyob rau saum toj, uas koom nrog cov saw ntawm cov amino acids raug tsim.
Thawj kauj ruam ntawm cov protein synthesis yog dab tsi?
STEP 1: Cov thawj kauj ruam hauv protein synthesis yog kev hloov pauv ntawm mRNA los ntawm DNA gene hauv lub nucleus. Qee lub sij hawm ua ntej, ntau hom RNA tau raug tsim los siv DNA tsim nyog. RNAs tsiv tawm ntawm lub nucleus mus rau hauv cytoplasm.

Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Dab tsi yog 4 kauj ruam nyob rau hauv tus txheej txheem ntawm transcription?
Transcription muaj plaub kauj ruam: pib. Lub DNA molecule unwinds thiab sib cais los tsim ib tug me me qhib complex. Elongation. RNA polymerase txav raws tus qauv strand, ua ke ntawm mRNA molecule. Kev txiav txim. Hauv prokaryotes muaj ob txoj hauv kev uas tau txiav tawm. Kev ua haujlwm
Thawj kauj ruam ntawm protein synthesis nyob qhov twg?
KAUJ RUAM 1: Thawj kauj ruam hauv kev tsim cov protein yog kev hloov pauv ntawm mRNA los ntawm DNA noob hauv lub nucleus. Qee lub sij hawm ua ntej, ntau hom RNA tau raug tsim los siv DNA tsim nyog. RNAs tsiv tawm ntawm lub nucleus mus rau hauv cytoplasm
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
Vim li cas thiaj nres thiab pib codons tsim nyog rau kev tsim cov protein?
Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, txheej txheem ntawm kev ua cov protein. Qhov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib. Qhov nres codon (los yog termination codon) cim lub vev xaib uas txhais lus xaus
