Nyob rau hauv cell biology, lub spindle apparatus yog hais txog lub cytoskeletal qauv ntawm eukaryotic hlwb uas tsim thaum lub sij hawm cell faib cais cov muam chromatids ntawm cov ntxhais hlwb.

Dab tsi yog mitotic spindle hauv biology?

Spindle fibers daim ntawv cov qauv protein uas faib cov khoom siv caj ces hauv lub cell. Lub spindle yog tsim nyog los sib faib cov chromosomes nyob rau hauv niam txiv cell mus rau hauv ob tug ntxhais hlwb thaum lub sij hawm ob hom ntawm nuclear faib: mitosis thiab meiosis. Thaum lub sij hawm mitosis, spindle fibers hu ua mitotic spindle.

Dab tsi yog mitotic spindle quizlet?

Ib qho kev sib sau ntawm microtubules thiab cov protein sib txuas uas koom nrog hauv kev txav ntawm chromosomes thaum mitosis

Lub mitotic spindle muaj dab tsi?

Abstract. Lub mitotic spindle, vim nws txoj kev tawm tsam, tau pom zoo rau ntau tshaj 100 xyoo. Muaj ntau ntawm microtubules thiab chromosomes, spindle kuj muaj ntau cov proteins uas nws lub luag haujlwm suav nrog biochemical thiab biophysical tswj ntawm mitosis.

Dab tsi yog mitotic spindle thiab nws lub luag haujlwm ua haujlwm hauv mitosis?

Lub mitotic spindle yog tus qauv uas tsim thaum lub sijhawm cell faib thiab cais cov chromosomes sib npaug. Hauv eukaryotic hlwb, lub mitotic apparatus yog tsim los ntawm ob centrosomes thiab spindle microtubules (Daim duab 43.9). Lub centrosome yog 1-2 μm hauv txoj kab uas hla.
