Txawm tias cell txoj kev loj hlob feem ntau yog ib qho txheej txheem tas mus li, DNA yog synthesized thaum lub sij hawm tsuas yog ib theem ntawm cov cell voj voog , thiab cov chromosomes replicated ces faib rau tus ntxhais nuclei los ntawm ib tug complex txheej xwm ua ntej. cell faib.
Tsis tas li ntawd, lub sijhawm twg ntawm lub voj voog ntawm tes yog DNA synthesized?
S theem
Kuj Paub, puas DNA synthesis tshwm sim hauv meiosis? Teb thiab piav qhia: DNA replication rau cell tshwm sim thaum Synthesis Phase ntawm meiosis . Cov theem no yog ib qho ntawm peb lub sijhawm Interphase theem ntawm meiosis.
Ib yam li ntawd, tej zaum koj yuav nug, qhov twg DNA synthesized nyob rau hauv lub cell?
DNA thiab Protein Synthesis Cov ntaub ntawv caj ces yog khaws cia rau hauv DNA nyob rau hauv lub nucleus thiab mitochondria ntawm hlwb . DNA Nws muaj ob txoj hlua ntawm nucleotides ntawm phospho deoxyribose qaum. Ob txoj hlua tsim ib ob lub helix uas ruaj khov los ntawm kev tsim cov hydrogen bonds ntawm nucleotide bases ntawm ob strands.
Vim li cas cov hlwb sib faib?
Cell faib rau ntau yam. Piv txwv li, thaum koj tawv koj lub hauv caug, cell faib hloov cov qub, tuag, lossis puas hlwb . Thaum cov kab mob loj hlob, nws tsis yog vim hlwb tau loj dua. Cov kab mob loj hlob vim hlwb yog kev faib los tsim ntau thiab ntau dua hlwb.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog txhais los ntawm lub voj voog ntawm tes lossis cell division voj voog?
Cell Cycle thiab Mitosis (hloov kho 2015) LUB CELL CYCLE Lub voj voog ntawm tes, lossis lub voj voog ntawm tes faib, yog cov xwm txheej uas tshwm sim hauv lub cell eukaryotic ntawm nws qhov tsim thiab lub sijhawm nws rov ua dua nws tus kheej. Interphase yog nyob nruab nrab ntawm lub sijhawm thaum lub cell faib
Puas yog qhib lub voj voog ib lub voj voog lossis kab lus?
Koj siv cov brackets thaum koj xav suav nrog qhov kawg, thiab koj pom qhov no nrog lub voj voog kaw / dot. Ntawm qhov tod tes, yog tias koj xav tshem tawm qhov kawg, koj siv aparenthesis, uas yog qhia los ntawm lub voj voog qhib
Cov ntsiab lus DNA hloov pauv li cas thaum lub sij hawm lub voj voog ntawm tes thiab mitosis?
Tus nqi ntawm DNA nyob rau hauv ib lub cell hloov tom qab txhua yam hauv qab no: fertilization, DNA synthesis, mitosis, thiab meiosis (Fig 2.14). Yog hais tias lub cell raug mitosis, txhua tus ntxhais cell yuav rov qab mus rau 2c thiab 2n, vim hais tias nws yuav tau txais ib nrab ntawm DNA, thiab ib tug ntawm txhua khub niam txiv chromatids
Lub neej voj voog ntawm fern txawv ntawm lub neej voj voog ntawm moss li cas?
Qhov txawv: -- Mosses yog cov nroj tsuag uas tsis muaj vascular; ferns yog vascular. - Gametophyte yog lub cim tseem ceeb hauv mosses; sporophyte yog lub cim tseem ceeb hauv ferns. - Mosses muaj cov txiv neej thiab poj niam sib cais gametophytes; fern gametophytes muaj txiv neej thiab poj niam qhov chaw ntawm tib tsob nroj
