Mi­too­si eli tu­man ja­kau­tu­mi­nen on osa so­lun elä­män­kier­toa, jon­ka vai­heet ovat seu­raa­vat:

• G1 = kas­vu­vai­he
• S = syn­tee­si­vai­he: pe­ri­mä kah­den­tuu
• G2 = val­mis­tau­tu­mi­nen mi­too­siin: solu­e­li­met kah­den­tu­vat, kro­mo­so­mien kro­ma­tii­ni­rih­mat pak­kau­tu­vat tii­viim­mäk­si, mik­ro­put­ket jär­jes­täy­ty­vät
• mitoosi
• sytokineesi: solu ja­kau­tuu lo­pul­li­ses­ti kah­tia; eläin­so­lul­la solu­kal­von ku­rou­tu­mi­sen kaut­ta – kas­vi­so­lul­la puo­lis­ko­jen vä­liin syn­tyy uusi solu­sei­nä
