Ribosomal RNA (rRNA) koom nrog ib pawg ntawm cov proteins tsim ribosomes. Cov txheej txheem nyuaj no, uas lub cev txav mus raws ib qho mRNA molecule, catalyze lub sib dhos ntawm cov amino acids rau hauv protein ntau chains. Lawv kuj khi tRNAs thiab ntau yam khoom siv molecules tsim nyog rau protein ntau synthesis.
Xav txog qhov no, lub luag haujlwm tseem ceeb ntawm RNA yog dab tsi?
Cov Lub luag haujlwm tseem ceeb ntawm RNA yog nqa cov ntaub ntawv ntawm cov amino acid ib ntus los ntawm cov noob mus rau qhov twg cov proteins tau sib sau ua ke ntawm ribosomes hauv cytoplasm. Qhov no yog ua los ntawm tus tub txib RNA (mRNA). Ib txoj hlua DNA ib leeg yog daim ntawv qhia rau mRNA uas tau sau los ntawm DNA strand.
Tsis tas li ntawd, dab tsi yog lub luag haujlwm ntawm DNA thiab RNA hauv kev tsim cov protein? DNA ua RNA ua Protein . Cov synthesis ntawm cov proteins tshwm sim nyob rau hauv ob theem ua ke: Transcription thiab Translation. Transcription tshwm sim nyob rau hauv lub cell nucleus thiab siv lub hauv paus ib theem zuj zus ntawm DNA tsim mRNA. Lub mRNA nqa cov lus los ua ib qho tshwj xeeb protein ntau tawm mus rau cytoplasm qhov twg kev txhais lus tshwm sim.
Kuj tseem paub yog, lub luag haujlwm ntawm cov protein synthesis yog dab tsi?
Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv los ua cov proteins , uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab muaj nuj nqi . Muaj ob yam tseem ceeb rau protein synthesis . Hauv kev sau ntawv, DNA tau theej rau mRNA, uas yog siv los ua tus qauv rau cov lus qhia ua protein ntau.
Lub ntsiab lus ntawm RNA hauv biology yog dab tsi?
Luv luv rau ribonucleic acid. Cov nucleic acid uas siv rau hauv cov txheej txheem metabolic tseem ceeb rau txhua kauj ruam ntawm kev tsim cov protein nyob hauv txhua lub hlwb thiab nqa cov ntaub ntawv caj ces ntawm ntau tus kab mob. Tsis zoo li ob-stranded DNA, RNA muaj ib txoj hlua ntawm nucleotides, thiab nws tshwm sim nyob rau hauv ntau qhov ntev thiab cov duab.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Puas yog txoj kev xav ua lub luag haujlwm hauv kev tshawb fawb?
Txoj kev xav tuaj yeem yog qhov pib ntawm koj qhov kev tshawb fawb, piv txwv li thaum koj qhov kev tshawb fawb yog hais txog kev sim kev tshawb xav. Kev tshawb xav tuaj yeem siv los ua ib qho cuab yeej, los pab piav qhia qee yam lossis ua kom paub cov ntaub ntawv
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Dab tsi organelle yog lub luag haujlwm rau kev thauj khoom hauv thiab tawm ntawm lub cell?
Function Of Cell Organelles A B cell membrane tswj kev txav mus rau hauv thiab tawm ntawm lub cell cytoplasm watery khoom uas muaj ntau cov ntaub ntawv koom nrog hauv cell metabolism endoplasmic reticulum ua txoj hauv kev rau kev thauj khoom thoob plaws hauv lub cell
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
