Protein synthesis yog txheej txheem tag nrho cov hlwb siv los ua cov proteins , qho yog lub luag haujlwm rau tag nrho cell qauv thiab kev ua haujlwm. Lub ribosome, uas yog ib compartment ntawm lub cell xav tau rau protein synthesis , qhia tRNA kom tau txais cov amino acids, uas yog lub tsev blocks ntawm cov proteins.
Ib yam li ntawd, yuav ua li cas tsis muaj protein synthesis?
Ribosomes muaj cov molecules hu ua RNA. Cov molecules tuav tag nrho cov lus qhia tsim nyog rau ribosomes ua protein synthesis los yog tus txheej txheem ntawm kev tsim cov proteins . Tsis muaj cov no cov proteins , DNA kho yuav tsis yog tshwm sim , ua rau kev hloov pauv thiab teeb meem xws li mob qog noj ntshav.
Tsis tas li ntawd, vim li cas cov protein synthesis hauv lub cell? Kev piav qhia: Ribosomes muaj nyob hauv cytoplasm thiab mitochondria's chloroplast. RNA pom hauv ribosomes ua lub luag haujlwm tseem ceeb hauv protein synthesis . Qhov no synthesis hu ua translation vim tus protein ntau compound yog tsim los ntawm cov amino acid thiab cov qauv ntawm cov amino acid yog decoded los ntawm noob.
Tsis tas li ntawd, dab tsi yog qhov yuav tsum tau rau cov protein synthesis?
Lwm qhov kev xav tau loj rau protein synthesis yog tus txhais lus molecules uas lub cev "nyeem" cov mRNA codons. Hloov RNA (tRNA) yog ib hom RNA uas ferries qhov tsim nyog cov amino acids coj mus rau ribosome, thiab txuas txhua cov amino acid tshiab mus rau qhov kawg, tsim cov polypeptide saw ib-los-ib.
Koj puas tuaj yeem tuag yam tsis muaj protein?
Kev noj zaub mov kom txaus txaus kom ua tau raws li qhov yuav tsum tau ua. Tab sis yog tias ib tug neeg nquag nquag lossis ua haujlwm ntau, nws tseem ceeb heev kom haus ntau dua protein ntau vim zog tsis muaj protein ntau lub cev yuav rhuav tshem cov leeg nqaij kom muaj zog. Luv luv mus dhau lub luag haujlwm protein ntau kev ua si hauv lub cev qhia tias tib neeg tsis tuaj yeem nyob tsis muaj nws.

Vim li cas txhua yam muaj sia yuav tsum muaj DNA?
Tag nrho cov kab mob uas muaj sia nyob yuav tsum muaj vim nws ua raws li cov khoom siv caj ces (muaj cov noob caj noob ces) uas khaws cov ntaub ntawv lom neeg. Tsis tas li ntawd, DNA encodes cov kab ke ntawm cov amino acid residues (rau protein synthesis) siv ib tug triplet code ntawm neucleotides (genetic code) tom qab transcribing rau RNA
Vim li cas cov txheej txheem ntawm cov protein synthesis tseem ceeb rau lub neej?
Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv los ua cov protein, uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Proteins tseem ceeb hauv txhua lub hlwb thiab ua haujlwm sib txawv, xws li koom nrog cov pa roj carbon dioxide rau hauv qab zib hauv cov nroj tsuag thiab tiv thaiv cov kab mob los ntawm cov tshuaj phem
Vim li cas tsiaj cov hlwb loj dua cov hlwb?
Feem ntau, cov noob qes loj dua nyob rau hauv kev sib piv rau cov tsiaj hlwb vim hais tias, feem ntau cov nroj tsuag paub tab muaj lub hauv paus loj vacuole uas occupies feem ntau ntawm cov ntim thiab ua rau lub cell loj dua tab sis lub hauv paus vacuole feem ntau yog tsis nyob rau hauv cov tsiaj hlwb. Yuav ua li cas cov phab ntsa ntawm ib tug tsiaj cell txawv ntawm ib tug cog cell?
Vim li cas cov hlwb yuav tsum muaj kev ruaj ntseg sab hauv?
Cov hlwb uas tsim cov kab mob muaj lub luag haujlwm loj - ua kom cov kab mob noj qab haus huv kom lawv loj hlob thiab rov tsim dua. Kev saib xyuas ntawm qhov ruaj khov, tsis tu ncua, sab hauv yog hu ua homeostasis. Koj lub hlwb ua qhov no los ntawm kev tswj hwm lawv qhov chaw nyob sab hauv kom lawv txawv ntawm qhov chaw sab nraud
Vim li cas cov hlwb muaj peev xwm sib txuas lus nrog lwm cov hlwb tseem ceeb?
Cov kev sib cuam tshuam no tso cai rau cov hlwb sib txuas lus nrog ib leeg hauv kev teb rau kev hloov pauv hauv lawv cov microenvironment. Qhov kev muaj peev xwm xa thiab tau txais cov teeb liab yog qhov tseem ceeb rau kev muaj sia nyob ntawm tes. Kev sib cuam tshuam ntawm cov hlwb tuaj yeem ruaj khov xws li cov uas ua los ntawm cov xov tooj ntawm tes
