Meiosis yog tus yam ntxwv los ntawm ib puag ncig ntawm DNA rov ua raws liob npaug ntawm cell faib, ua rau cov kab mob haploid. Kev hla dhau ntawm DNA ua rau muaj kev sib pauv caj ces ntawm cov noob ntawm niam thiab txiv DNA.
Puas yog DNA rov ua dua tshiab hauv mitosis lossis meiosis?
Ceeb toom: DNA replication tshwm sim tsuas yog ib zaug hauv meiosis thiab mitosis txawm hais tias tus naj npawb ntawm tes faib yog ob hauv meiosis thiab ib qho hauv mitosis uas ua rau cov lej sib txawv. ntawm cov hlwb haploid nyob rau hauv ob qho tib si txheej txheem.
DNA replicated hauv meiosis yog theem twg?
S theem ntawm lub voj voog ntawm tes tshwm sim thaum lub sijhawm sib cuam tshuam, ua ntej mitosis lossis meiosis, thiab yog lub luag haujlwm rau kev sib txuas lossis rov ua dua ntawm DNA. Ua li no, cov khoom siv caj ces ntawm ib lub xovtooj yog ob npaug ua ntej nws nkag mus rau mitosis lossis meiosis, tso cai kom muaj DNA txaus los faib rau hauv cov menyuam ntxhais.
YPuas DNA rov ua dua ntawm meiosis thiab meiosis II?
Cov gametes no yog tsim los ntawm meiosis, tshwj xeeb ntawm tes faib thaum lub sijhawm ib puag ncig ntawm DNA rov ua raws li ob qho kev sib cais ntawm chromosome, Meiosis I (MI) thiab Meiosis II (MII). … Txawm li cas los xij, DNA replication yuav tsum nyob twj ywm inhibited ntawm MI thiab MII.
Puas DNA rov ua dua hauv mitosis?
txheej txheem no suav nrog rov ua dua ntawm cov cell's chromosomes, kev cais ntawm DNA theej, thiab sib cais ntawm niam txiv lub xov tooj ntawm cytoplasm.… Qhov tshwm sim ntawm binary fission yog ob lub hlwb tshiab uas zoo ib yam li qub cell.
