Synthesis . Cov synthesis ntawm cov ribosomes nws tus kheej yog txheej txheem nyuaj heev, yuav tsum muaj kev sib koom tes tso tawm los ntawm ntau ntau cov noob encoding ribosomal ua proteins thiab rRNAs. Thaum assembled, yuav luag tiav ribosomal ua Cov subunits raug xa tawm tawm ntawm lub nucleus thiab rov qab mus rau hauv cytoplasm rau cov kauj ruam kawg ntawm kev sib dhos.
Yog li ntawd, qhov twg yog ribosomes synthesized?
Hauv cov kab mob kab mob, ribosomes yog synthesized nyob rau hauv lub cytoplasm los ntawm transcription ntawm ntau yam ribosome gene operons. Hauv eukaryotes, cov txheej txheem yuav siv ob qho tib si hauv cell cytoplasm thiab hauv nucleolus, uas yog thaj tsam hauv lub cell nucleus.
Ib tug kuj tseem nug, dab tsi yog ribosome thiab nws txoj haujlwm? Muaj nuj nqi ntawm Ribosomes . Ribosomes yog cov qauv cell uas ua rau cov protein. Protein xav tau rau ntau lub cell muaj nuj nqi xws li kho kev puas tsuaj los yog coj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom ntab hauv cytoplasm lossis txuas rau endoplasmic reticulum. Proteins yog ib feem tseem ceeb ntawm txhua lub hlwb.
Xav txog qhov no, ribosome tsim li cas?
Eukaryote cov ribosomes yog tsim thiab sib sau ua ke hauv cov nucleolus. Ribosomal cov proteins nkag mus rau hauv nucleolus thiab ua ke nrog plaub rRNA strands los tsim ob ribosomal ua subunits (ib qho me me thiab ib qho loj) uas yuav ua kom tiav ribosome (saib daim duab 1).
Dab tsi yog ribosomes hauv biology?
-sōm'] Ib tug kheej kheej-zoo li tus qauv nyob rau hauv lub cytoplasm ntawm ib tug cell uas yog tsim ntawm RNA thiab protein thiab yog qhov chaw ntawm protein synthesis. Ribosomes yog dawb nyob rau hauv lub cytoplasm thiab feem ntau txuas mus rau daim nyias nyias ntawm endoplasmic reticulum. Ribosomes muaj nyob rau hauv ob qho tib si eukaryotic thiab prokaryotic hlwb.

Lub hauv paus dogma ntawm protein synthesis yog dab tsi?
Lub hauv paus dogma yog lub hauv paus ntsiab lus los piav qhia txog kev ntws ntawm cov ntaub ntawv caj ces los ntawm DNA rau RNA rau cov protein. Thaum cov amino acids koom ua ke los ua ib qho protein molecule, nws hu ua protein synthesis. Txhua cov protein muaj nws tus kheej cov lus qhia, uas yog encoded nyob rau hauv seem ntawm DNA, hu ua noob
Dab tsi yog cov tshuaj tiv thaiv synthesis?
Cov tshuaj tiv thaiv synthesis yog ib hom tshuaj tiv thaiv uas muaj ntau yam reactants sib xyaw ua ib yam khoom. Synthesis tshwm sim tso tawm lub zog nyob rau hauv daim ntawv ntawm tshav kub thiab lub teeb, yog li lawv yog exothermic. Ib qho piv txwv ntawm cov tshuaj tiv thaiv synthesis yog tsim cov dej los ntawm hydrogen thiab oxygen
Dab tsi yog siv hauv DNA replication thiab protein synthesis?
Kev sau ntawv. Kev sau ntawv yog cov txheej txheem uas DNA tau theej (tshaj tawm) rau mRNA, uas nqa cov ntaub ntawv xav tau rau kev tsim cov protein. Kev hloov pauv yuav tshwm sim hauv ob kauj ruam dav. Ua ntej, ua ntej tus tub txib RNA yog tsim, nrog rau kev koom tes ntawm RNA polymerase enzymes
Dab tsi yog qhov chaw thiab P site ntawm ribosome?
Qhov chaw A yog qhov chaw nkag rau aminoacyl tRNA (tshwj tsis yog thawj aminoacyl tRNA, uas nkag mus rau ntawm P site). P site yog qhov chaw peptidyl tRNA tsim nyob rau hauv ribosome. Thiab E qhov chaw uas yog qhov chaw tawm ntawm tam sim no tsis muaj nqi tRNA tom qab nws muab nws cov amino acid rau cov saw peptide loj hlob
Dab tsi yog ribosome thiab nws txoj haujlwm?
Kev ua haujlwm ntawm Ribosomes. Ribosomes yog cov qauv ntawm tes uas ua rau cov protein. Protein xav tau rau ntau lub xovtooj ntawm tes xws li kho kev puas tsuaj lossis tswj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom nyob hauv lub cytoplasm lossis txuas rau endoplasmic reticulum. Proteins yog ib feem tseem ceeb ntawm txhua lub hlwb
