Isakhi pool - value core lwesintu

Ukuvela izinhlobo ezintsha izidalwa eziphilayo kungenzeka kuphela uma akhona bayohlanganyela "zifiki" ezakhini zabo zofuzo. Okungukuthi usetha of amino acid, okuyinto zigcinwa kuma-chromosome ka wonke amangqamuzana aphilayo. Zonke izakhi zofuzo sonke isintu kuyisikhalo yasebhange. It kuvela ukuthi ichibi isakhi sofuzo - iqoqo idatha agcwele zonke izidalwa ezingabantu yesikhathi esidlule, zamanje nezesikhathi esizayo.

Lapho lolu lwazi kugcinwa

Ama-chromosomes e uqobo le nuclei amaseli. ezihlukahlukene ngasinye has iqoqo layo eliyingqayizivele obhekene yayo umsebenzi. Ngokuvamile ama-chromosome kuthiwa run by izinqubo ezenzeka yeseli encane eyodwa futhi wonke umzimba. Kungcono eziqhathanisa computer, ngoba zonke izenzo ezizokwenzeka iseli, sebevele bhalisiwe, njengasezulwini uhlelo lwekhompyutha. Lapho ihlukaniswe isethi ezimbili ezibalulekile liphindwe kabili futhi iya ngamunye lakha amangqamuzana amasha nawo. It kuvela ukuthi zonke izinto eziphilayo ukuphila ithola ulwazi mayelana nazo zonke izidalwa bohlobo lwazo, egcinwe ezakhini zofuzo.

Isimiso somuntu isakhi sofuzo pool - lonke iqoqo izakhi zofuzo

Eplanethini ayizigidi zezinkulungwane ezimbalwa abantu. Kasibili wonke umuntu angakwazi ozibongayo awayo zofuzo. Lolu lwazi ngabanye futhi eyingqayizivele. Isiqalo nesigcino idatha, okuyinto ebiyelwe kuma-chromosome zabantu, futhi wechibi isakhi sofuzo lwesintu. It ihlukaniswe yaba amaqembu ngokusekelwe uhlanga. Ngokwesibonelo, ichibi isakhi sofuzo se-isizwe Russian - ulwazi ezinkulu ezimayelana amasethi wama-chromosomes zabantu lokhu isizwe.

Kuyini ukubaluleka umqondo

Leli chibi isakhi sofuzo - kungenzeka ukuba adlulisele izimpawu yobuhlanga izizukulwane ezizayo. Lapho ubukhulu labantu kuyehla, izimo ukubhujiswa kwayo okugcwele. Okungukuthi, kukhona "abantu abaningi ezibucayi" ezithile wechibi zofuzo. Uma abantu ukhawulile zazo siqu, ukuthi uhlanga inganyamalala ebusweni Earth. Lokhu kusebenza sonke isintu. ukukhiqizwa kabusha njalo kuphela kunomthelela khona okuqhubekayo zinhlobo njengoba enjalo. Offset izakhi zofuzo phakathi kokukhulelwa unesibopho ukubukeka yezinguquko ezintsha. Ukuze udlale ukuba okuqhubekayo, abathwali ukwaziswa kwezakhi zofuzo kumele kwanele, futhi kudingeka ukuba zofuzo zivumela izidalwa ukwanda. It kuvela ukuthi ichibi isakhi sofuzo - imayelana kwezempilo nokuhlanzeka leqembu yobuhlanga noma lwesintu lulonke.

Ingqikithi ulwazi oluqukethwe kuma-chromosome

Zofuzo banesibopho ngokuvamile wonke umzimba futhi hhayi kuphela. umbala wamehlo noma izinwele, ibala kanye umzimba shape kungenxa yolwazi ngofuzo, ie isethi wama-chromosomes ukuthi ingane ithola kubazali bakhe. Ngaphezu kwalokho, yena namanje uthola amathuba yokuzuza isifo. izingxabano phezu ifa yesimo senhliziyo ziyaqhubeka. Kodwa umzimba womuntu awuwona ngempela ephelele, futhi ngokuvamile onezinkinga. umsebenzi sokuzala nako. Ngenxa ukuhlukahluka ingane angathola isethi obonakele wama-chromosomes, lokhu kungabangela isifo wezakhi. Lokhu iqoqo ngiwunike inzalo yakhe, futhi lokhu usongo lonke isakhi sofuzo pool. Yiqiniso, ukwehluleka eyodwa ngeke abhubhise esintwini. Kodwa uma lokho kwephula zisabalele, is sinciphisa ukuba khona kwalezi zilwane zikhona, ngoba uchungechunge ifa lingenxa okuqhubekayo. Isayensi lizama ukuthola izindlela zokunqanda isakhi sofuzo isifo, kodwa uma nje uhlala ezingeni lamaphupho, ngakho ekulondolozweni kwezindawo iphila isakhi sofuzo pool lwesintu - omunye imisebenzi esemqoka.
