Qhov no suav nrog txheej txheem hu ua meiosis. Thaum lub sij hawm tsis zoo, lub cev teb los ntawm kev nkag mus rau theem ntxov (thawj theem ntawm sporulation) ntawm sporulation. Thaum lub sij hawm no, cell division txheej txheem hloov ntawm lub mitotic voj voog nyob rau hauv G1 (Ib theem interphase) thiab nkag mus rau theem S nyob rau hauv meiosis.
Yuav ua li cas yog qhov kev txiav txim ntawm theem ntawm sporulation?
Maturation and release of endospore In-folding of the plasma membrane to enclose a copy of DNA, forming forespore and septum Spore coat formation Replication of DNA + Deposition ntawm spore cortex Engulfment ntawm forespore nrog ob daim nyias nyias.
thawj kauj ruam hauv kev tsim cov kab mob yog dab tsi?
Stage I: Activation, txhais tau tias yog kev pib lossis ua rau cov txheej txheem hauv kev teb rau cov khoom noj khoom haus ntxiv uas tshwm sim thaum cov germinating molecules, suav nrog cov amino acids uas tsis muaj molecular-yuag, suab thaj, thiab purine nucleosides, yog paub los ntawm germination receptors (GRs) nyob rau hauv lub puab membrane ntawm lub spore.
Dab tsi yog qhov germination ntawm endospores thiab nws pib quizlet li cas?
-Germination (tus txheej txheem uas cov endospores rov qab mus rau lub xeev vegetative) yog ua los ntawm PHYSICAL LOSSIS CHEMICAL kev puas tsuaj rau lub tsho endospores.
kab mob sporulation txhais li cas?
Sporulation yog cov lus teb hnyav ua los ntawm qee cov kab mob, feem ntau Firmicutes, teb rau kev ntxhov siab heev. Thaum lub sij hawm sporulation,cov cell loj hlob (tseem hu ua ib lub cell vegetative) yuav forego ib txwm cellular faib los ua ib qho endospore.
