Document Summary
There has to be asymmetri cell division and a pre-spore is engulefed by the mother cell and it developes and the cell lysis, releasing the spore. Spo0a becomes phosphorylated, and theres lots of sigma factors and alternative complex involved in this process. Sigma f is important in transcribing genes important for the spore formation, and different sigma factors are also coming into play in the mother cell to cause spore formation. The process of the spore coming back and forming germinating cells, and its called germination where the spore is degraded so it can start trepliating cells again. Flagella (cid:373)ediate s(cid:449)i(cid:373)(cid:373)i(cid:374)g a(cid:374)d s(cid:449)a(cid:396)(cid:373)i(cid:374)g. t(cid:449)it(cid:272)hi(cid:374)g is (cid:373)ediated (cid:271)y pili, a(cid:374)d (cid:449)e do(cid:374)"t k(cid:374)o(cid:449) ho(cid:449) glidi(cid:374)g works. If they produce the green circle, they can swim. The flagella are 2nm wide byt 20nm long. On the outside, theres a long filament with a capsule on the end. Theres a flexible link to the machinery that"s o(cid:374) the i(cid:374)side of the ell.
