Lub nucleus muaj tag nrho cov khoom siv caj ces rau lub cell eukaryotic, tab sis cov khoom siv caj ces no yuav tsum tau tiv thaiv. Thiab nws tau tiv thaiv los ntawm lub nuclear membrane, uas yog ob daim nyias nyias uas kaw tag nrho cov khoom siv noob caj noob ces nuclear thiab tag nrho lwm cov khoom ntawm lub nucleus.
Dab tsi tiv thaiv thiab puag ncig lub nucleus?
Lub nucleus nyob ib puag ncig los ntawm membrane hu ua lub hnab ntawv nuclear, uas tiv thaiv DNA thiab cais cov nucleus los ntawm lwm lub cell.
Lub nucleus puas tiv thaiv lub nucleus?
Nucleus Structure
Nuclear envelope - Lub hnab ntawv nuclear yog tsim los ntawm ob daim nyias nyias: daim nyias nyias thiab sab hauv daim nyias nyias. Lub hnab ntawv tiv thaiv cov nucleus los ntawm qhov seem ntawm cytoplasm hauv cell thiab khaws cov molecules tshwj xeeb hauv cov nucleus kom tsis txhob tawm mus.
Dab tsi pab lub nucleus?
Proteins yog qhov tseem ceeb vim lawv muaj lub luag haujlwm rau cov qauv, kev ua haujlwm, thiab kev tswj hwm ntawm lub cev cov ntaub so ntswg thiab lub cev. Yog li ntawd, txhua yam organelle uas koom nrog hauv kev tsim thiab faib cov proteins yuav ncaj qha pab lub nucleus hauv txoj haujlwm no.
Cov nucleus yog dab tsi?
Zoo li lwm cov cellular organelles, lub nucleus yog ib puag ncig los ntawm membrane hu ua lub hnab ntawv nuclear. Qhov no membranous npog muaj ob sab lipid bilayers uas nyob ib sab nrog ib qho chaw nyias nyias nyob nruab nrab ntawm lawv. Kev nthuav dav ob lub bilayers no yog nuclear pores.
