Colcemid Solution ntes mitotic hlwb hauv metaphase.
Qhov twg yog qhov chaw kuaj xyuas uas tiv thaiv mitosis thaum pib yog tias tag nrho cov chromosomes tsis tau rov ua dua?
Lub Kev Pom Tsis Zoo DNA Tiv thaiv kev nkag mus rau hauv MitosisCells uas tsis rov ua dua tag nrho lawv cov chromosomes tsis nkag mus rau mitosis. Kev ua haujlwm ntawm qhov chaw kuaj xyuas no suav nrog kev lees paub ntawm DNA tsis tau txuas ntxiv thiab inhibition ntawm MPF ua kom.
txheej txheem twg tshwm sim hauv metaphase?
Metaphase yog ib theem hauv lub voj voog ntawm tes uas tag nrho cov khoom siv caj ces yog condensing rau hauv chromosomes. Cov chromosomes ces pom tau. Thaum lub sij hawm no, lub nucleus ploj mus thiab cov chromosomes tshwm nyob rau hauv lub cytoplasm ntawm lub cell.
Colcemid nres kev faib cell li cas?
Demecolcine (INN; tseem hu ua colcemid) yog cov tshuaj siv tshuaj khomob. … Thaum lub sij hawm faib cell, demecolcine inhibits mitosis ntawm metaphase los ntawm inhibiting spindle tsim.
Lub luag haujlwm ntawm colcemid yog dab tsi?
Colcemid yog siv hauv kev tshuaj ntsuam chromosome thaum lub sij hawm lymphocyte karyotyping thiab hauv amniotic kua cell chromosome tsom los ntawm kev tiv thaiv spindle tsim thaum lub sij hawm mitosis, ua rau metaphase ntes. Metaphase yog lub sijhawm zoo tshaj plaws ntawm mitosis rau microscopically pom cov chromosomes.
