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.
