Hauv Cell faib voj voog ntawm budding poov xab, PIB yog hais txog cov txheej xwm sib txuas nruj heev uas npaj a cell rau budding thiab DNA replication, thiab FINISH qhia txog cov xwm txheej cuam tshuam los ntawm qhov cell tawm ntawm mitosis thiab faib ua niam thiab tus ntxhais hlwb.

Hauv qhov no, dab tsi yog txhais los ntawm lub voj voog ntawm tes?

Cov cell voj voog , los yog cell - faib lub voj voog , yog series ntawm cov xwm txheej uas tshwm sim hauv ib cell ua rau duplication ntawm nws DNA (DNA replication) thiab faib cytoplasm thiab organelles los tsim ob tug ntxhais hlwb.

Tsis tas li ntawd, dab tsi tshwm sim hauv g1 S thiab g2? Interphase yog tsim los ntawm G1 theem (cell loj hlob), ua raws li S theem (DNA synthesis), ua raws li G2 theem (cell loj hlob). Thaum kawg ntawm interphase los ntawm mitotic theem, uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau tsim ntawm ob tug ntxhais hlwb.

Ib yam li ntawd, tib neeg nug, dab tsi yog g1 theem ntawm lub voj voog ntawm tes?

G1 Phase. G1 yog theem nrab nyob rau lub sijhawm nruab nrab ntawm qhov kawg ntawm kev faib cell hauv mob mitosis thiab pib ntawm DNA replication thaum lub sij hawm S theem . Thaum lub sij hawm no, lub cell loj hlob nyob rau hauv kev npaj rau DNA replication, thiab tej yam intracellular Cheebtsam, xws li cov centrosomes undergo replication.

Dab tsi yog 3 cell voj voog checkpoints?

Tam sim no, muaj peb paub chaw kuaj xyuas ua: g1 chaw kuaj mob , tseem hu ua kev txwv lossis pib chaw kuaj mob los yog (Major Chaw kuaj xyuas ); G2/M chaw kuaj mob ; thiab metaphase chaw kuaj mob , tseem hu ua spindle chaw kuaj mob.
