Lub voj voog ntawm tes muaj ob theem loj: interphase thiab mitotic theem (Daim duab 1). Thaum interphase, cell loj hlob thiab DNA yog replicated. Thaum lub sij hawm mitotic theem, lub replicated DNA thiab cov ntsiab lus cytoplasmic tau sib cais, thiab cov cell faib.

Yog li ntawd, koj yuav piav qhia txog cov yam ntxwv tseem ceeb ntawm S hauv lub voj voog ntawm tes li cas?

S theem. Hauv S phase, ua cell synthesizes ib daim qauv ntawm DNA hauv nws cov nucleus. Nws kuj tseem duplicates lub microtubule-organizing qauv hu ua centrosome. Cov centrosomes pab cais DNA thaum lub sij hawm M.

Ib sab saum toj no, dab tsi yog qhov piv txwv ntawm lub voj voog ntawm tes? Cov cell voj voog Muaj ntau ntau repetitions ntawm cellular kev loj hlob thiab kev loj hlob. Nrog qee qhov kev zam (rau piv txwv , ntshav liab hlwb ), tag nrho cov hlwb ntawm cov muaj sia nyob undergo a cell voj voog . Mitosis yog theem ntawm tus kab mob cell voj voog thaum lub sij hawm uas cell faib ua ob tug ntxhais hlwb.

Kuj kom paub, koj yuav piav qhia txog cov yam ntxwv tseem ceeb ntawm g1 hauv lub voj voog ntawm tes li cas?

Thaum lub sij hawm loj hlob theem 1, los yog G1 , cov cell loj hlob nyob rau hauv loj nyob rau hauv teb rau tej yam proteins hu ua loj hlob yam. Ib daim qauv ntawm cov cell cov DNA yog tsim thaum lub sij hawm synthesis, los yog S theem. Kev loj hlob kuj tshwm sim thaum lub sij hawm kev loj hlob thib ob, lossis G2.

Dab tsi yog cov yam ntxwv ntawm interphase?

Interphase hais txog txhua theem ntawm lub voj voog ntawm tes uas tsis yog mitosis. Thaum interphase , cellular organelles ob npaug ntawm tus lej, DNA replicates, thiab protein synthesis tshwm sim. Cov chromosomes tsis pom thiab DNA tshwm li uncoiled chromatin.
