Morero oa mitosis ke ofe?
Sele ke karolo ea mantlha e sebetsang e tsamaisang ts'ebetso ea likokoana-hloko ea tsohle ho tloha ho libaktheria le li-fungus ho ea ho maruarua a maputsoa le li-redwoods tse telele. Meetso ena e matla, e rarahaneng, empa e le microscopic e fihlela kholo le nchafatso ea likokoana-hloko tse ngata ka mitosis, ts'ebetso e makatsang e fetolang sele ho ba lisele tse peli.
Tlhaloso e nepahetseng
Ea mantlha morero ea mitosis ho ipapisitse le moelelo oo uo sebelisang ho lentsoe lena. Hangata Mitosis e tšohloa ka ho pharaletseng e le polelo e tšoanang le ea karohano ea sele. Ka kutloisiso ena, mitosis ke mokgoa oo seleng e itlhahisang ka ona ho etsa sele ya moradi e tshoanang ka lefutso.
Tlhaloso e nepahetseng haholoanyane ea 'mitosis' ke ts'ebetso eo khubu e ikatisang ka eona 'me e ikarola ho li-nuclei tse peli tse nang le likopi tse nepahetseng tsa liphatsa tsa lefutso.
Motsoako o mocha
Mitosis, ho latela tlhaloso e nepahetseng, e na le mekhahlelo e mene ea mantlha: prophase, metaphase, anaphase le telophase. Mekhahlelo ea pele e meraro e shebane haholo le karohano le tlhophiso ea li-chromosome tse ileng tsa kopitsoa nakong ea interphase, e tlang pele ho mitosis.
Li-chromosome ke limolek'hule tse telele tse nang le tlhaiso-leseling ea lefutso ka mofuta oa deoxyribonucleic acid, e tsejoang ka hore ke DNA.
Nakong ea telophase , ho ba le khubung e ncha e potileng sehlopha ka seng sa li-chromosome, e leng se hlahisang li-nuclei tse peli tse tšoanang le liphatsa tsa lefutso. Mitosis e qala ho hlaha nakong ea karohano ea sele hobane sele e ncha e ke ke ea phela ntle le konokono e nang le tlhaiso-leseling ea lefutso e bohlokoa bakeng sa taolo ea mesebetsi ea lisele.
Sele e le 'ngoe, lisele tse peli
Karohano ea sele e qala ka mitosis mme e qetella ka cytokinesis, moo mokelikeli oa cellular, o tsejoang e le cytoplasm, o arohanang ho theha lisele tse peli tse potileng li-nuclei tse peli tse entsoeng nakong ea mitosis.
Liseleng tsa liphoofolo, cytokinesis e etsahala e le mokhoa o fokolang o qetellang o pepeta sele ea motsoali a le mong likarolo tse peli. Lisele tsa semela, cytokinesis e etsoa ke poleiti ea lisele e bopehang bohareng ba sele mme qetellong e arohanngoa ka lisele tse peli.
Ha ho na Nucleus, ha ho na mitosis
Tlhaloso e nepahetseng ea mitosis e le karohano ea nyutlelie ho fapana le karohano e akaretsang ea lisele e thusa ho hlakisa ntlha ea bohlokoa - mitosis e sebetsa feela liseleng tsa eukaryotic. Lisele tsohle li oela likarolong tse peli tse pharalletseng: prokaryotic le eukaryotic. Libaktheria le libopuoa tse nang le sele e le 'ngoe tse tsejoang e le archaea ke lisele tsa prokaryotic,' me lintho tse kang limela, liphoofolo le li-fungus li na le lisele tsa eukaryotic.
E 'ngoe ea liphapang tse khethollang lipakeng tsa mefuta ena e' meli ea lisele boteng ba mantlha: lisele tsa eukaryotic li na le mokokotlo o fapaneng, 'me lisele tsa prokaryotic ha li na tsona. Ka lebaka leo, mitosis e ke ke ea sebetsa ho karohano ea lisele tsa prokaryotic, eo ho thoeng e bitsoa cleavage ea binary.
