Ribosomes thiab rRNA

Ribosomes muaj ob lub subunits ua los ntawm RNAs thiab cov proteins . Ribosomes yog cov cell protein ntau - koom ua ke tshuab . Lawv txoj haujlwm yog los txuas protein ntau tsev blocks (amino acids) ua ke los ua cov proteins nyob rau hauv ib qho kev txiav txim sau tawm hauv tub txib RNA (mRNA).

Hauv qhov no, lub tshuab protein yog dab tsi?

Protein tshuab . Txhawm rau ua tiav cov haujlwm no, cov proteins feem ntau ua haujlwm ua ke nrog lwm tus cov proteins los yog nucleic acids li multicomponent "molecular tshuab " -- cov qauv uas haum ua ke thiab ua haujlwm hauv kev tshwj xeeb, kaw-thiab-qhov tseem ceeb.

Kuj Paub, dab tsi tswj cov protein synthesis? Protein synthesis yog ib qho tseem ceeb ntawm lub cim xeeb tsim, thiab E2 tswj tus synthesis ntawm nov cov proteins los ntawm yam tsawg kawg yog ob qhov sib txawv estrogen receptor (ER)-kev kho kom haum xeeb mechanisms: txoj hauv kev classical genomic thiab kev ua kom tsis zoo ntawm cov xovtooj ntawm tes.

Hauv qhov no, ua li cas cov protein ua?

Cov ntaub ntawv tsim tawm a protein ntau yog encoded hauv cell DNA. Thaum a protein ntau yog tsim, ib daim qauv ntawm DNA yog ua (hu ua mRNA) thiab daim ntawv no raug thauj mus rau ribosome. Ribosomes nyeem cov ntaub ntawv hauv mRNA thiab siv cov ntaub ntawv ntawd los sib sau cov amino acids rau hauv a protein ntau.

Puas yog cov tshuab hlwb?

Yog, biological cell yog a tshuab . Cov cell siv lub zog ATP txhawm rau ua tiav tag nrho nws cov haujlwm, yog nws Replication, transcription thiab txhais cov noob rau synthesize proteins thiab lwm yam DNA muaj tag nrho cov ntaub ntawv rau ib tug cell ua haujlwm kom raug thiab ua tau zoo.
