Ribosomes yog qhov chaw uas cov proteins yog synthesis. Cov txheej txheem kev hloov pauv qhov twg cov lej ntawm DNA tau theej tshwm sim hauv cov nucleus tab sis cov txheej txheem tseem ceeb ntawm kev txhais cov lej ntawd los ua lwm cov protein tshwm sim hauv ribosomes.
Cov proteins ua nyob rau hauv lub cell organelle nyob qhov twg?
Proteins tau sib sau ua ke ntawm organelles hu ua ribosomes. Thaum cov proteins yog destined los ua ib feem ntawm lub cell membrane los yog xa tawm ntawm lub cell, lub ribosomes assembling lawv txuas mus rau lub endoplasmic reticulum, muab nws ib tug ntxhib tsos.
YPuas yog cov proteins tsim hauv cov nucleus?
Lub Nucleus & Nws Cov Qauv Yog li ntawd, lub nucleus tsev hauv lub cell DNA thiab coj cov synthesis ntawm cov proteins thiab ribosomes, cellular organelles lub luag hauj lwm rau protein synthesis.
Yuav ua li cas cov proteins pom nyob rau hauv lub nucleus?
Yuav kom npaj cov DNA ntau hauv cov nucleus, cov proteins hu ua histones txuas rau chromosomes; DNA yog qhwv ib ncig ntawm cov histones los tsim ib tug qauv zoo li cov hlaws dai ntawm ib txoj hlua. Cov protein-chromosome complexes hu ua chromatin. Daim duab 4.3C.
Cov proteins ua hauv DNA nyob qhov twg?
Yuav kom lub cell tsim cov proteins no, cov noob tshwj xeeb hauv nws DNA yuav tsum xub muab tso rau hauv cov molecules ntawm mRNA; Tom qab ntawd, cov ntawv sau tseg no yuav tsum tau muab txhais ua cov saw hlau ntawm cov amino acids, uas tom qab ntawd quav rau hauv cov proteins uas ua haujlwm tau zoo.
