Lub voj voog ntawm tes muaj peb theem uas yuav tsum tshwm sim ua ntej mitosis, los yog cell division, tshwm sim. Cov no peb theem yog collectively hu ua interphase . Lawv yog G1, S, thiab G2. G sawv rau qhov sib txawv thiab S sawv rau kev sib txuas.

Sib tham, yuav ua li cas tshwm sim thaum lub sij hawm 3 theem ntawm interphase?

Muaj peb theem ntawm interphase : G1 (thawj qhov sib txawv), S (synthesis ntawm DNA tshiab), thiab G2 (thib ob qhov sib txawv). Cells siv feem ntau ntawm lawv lub neej hauv interphase , tshwj xeeb hauv tus S theem qhov twg cov khoom siv caj ces yuav tsum tau theej. Lub cell loj hlob thiab ua haujlwm biochemical, xws li protein synthesis, hauv lub G1 theem.

Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim hauv txhua theem ntawm interphase? Interphase yog tsim los ntawm G1 theem (kev loj hlob ntawm tes), ua raws li S theem (DNA synthesis), ua raws li G2 theem (kev loj hlob ntawm tes). Thaum kawg ntawm interphase los ntawm mitotic theem , uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau kev tsim ntawm ob tug ntxhais hlwb.

Hais txog qhov no, dab tsi tshwm sim thaum g1 theem ntawm interphase?

Cov G1 Phase feem ntau hu ua kev loj hlob theem , vim lub sijhawm no hauv uas ib tug cell loj hlob. Thaum qhov no theem , lub cell synthesizes ntau yam enzymes thiab cov as-ham uas xav tau tom qab rau DNA replication thiab cell division. Cov G1 Phase kuj yog thaum cov hlwb tsim cov protein ntau.

Tus txheej txheem ntawm interphase yog dab tsi?

Thaum interphase , lub cell luam nws DNA hauv kev npaj rau mitosis. Interphase yog 'kev ua neej nyob txhua hnub' lossis theem metabolic ntawm lub cell, uas lub cell tau txais cov as-ham thiab metabolizes lawv, loj hlob, nyeem nws cov DNA, thiab ua lwm yam "ib txwm" cell functions.
