Mutagens enomthelela umuntfu lakhetsa kuphila ngato. Mutagen - ke ..

Mhlawumbe, wonke umuntu ajwayelekile igama, njengoba mutagen. Le into, okungaba bemvelo ezahlukene kanye ezahlukene ukuchayeka kwemibala. Bangaphinde sonakalise indalo nabantu. Kodwa ngokuvamile izakhiwo zabo ezisetshenziswa ezinhle emikhakheni lehlukene zokuphila.

Uyini mutagen

Wonke umuntu umqondo wabo siqu ngalokho ayinto kuyinto. Kodwa empeleni, mutagen - into ebanga ukuguqulwa ziphikelele isakhiwo umzimba. Lezi zinguquko ngokuvamile ngofuzo subsequent zukulwane.

Mutagens kukhona acid ezithile, compounds ahlukahlukene, amalungiselelo ngisho ezithile yokukhishwa kwemisebe. Futhi, bangase babe ezinye izinhlobo amagciwane. Mutagen - incazelo jikelele zezici kungase kuguqulwe izakhi zofuzo kunoma yiziphi umzimba, eziqala ama-bacterium nezitshalo kokuqeda futhi indoda. Umthamo incike ukushuba izinguquko.

izinhlobo mutagens

Namuhla, kunezinhlobo ezintathu ezaziwayo mutagens: ngokomzimba, zamakhemikhali nezinto eziphilayo. Isigaba sokuqala sihlanganisa zonke emisebeni ionizing. Lokhu-X ray kanye gamma ray, neutrons, ama-proton, oku-ultraviolet. Nokho, kuyathakazelisa ukuthi ngandlela-thile esitebeleni lokushisa eliphezulu kakhulu noma eliphansi futhi kuba nethonya izinguquko ekwakhekeni nasekumeni komzimba, ukuguqulwa mancane okukhulu.

Esinye isigaba - chemical mutagens. Lezi zilimi zazihlanganisa DNA angaphandle alkylating kwakwakhe (dimethylsulfate, lwesinaphi njll)., Oxide acid, imithi yokubulala izinambuzane, acridine udayi, formaldehyde, abanye alkaloids futhi peroxides organic. Lihlanganisa nezinye izidakamizwa eziningi izinto, ubunjalo okuyinto ingakamiswa uphenyo. mutagens eziphilayo zingaba amagciwane, ezinye izitshalo futhi izinto ezishintshwe izakhi.

Mutagens nabantu: engcupheni

Ososayensi bavame ukusebenzisa mutagens ukuze kuzuze umphakathi, isibonelo, bajwayele abalimi. Kodwa okuningi ithonya labo alivumi. Ngokuthenga eziningi imikhiqizo, bathole imithi, ama yokuhlanza imikhiqizo kanye izinto zasendlini, abantu bekhanyisa mutagens, okubangela lokhu ukulinyazwa emzimbeni. Ngokuvamile kwenzeka kungabonakali komuntu futhi kubonakala kuphela isizukulwane esilandelayo. Ngeshwa, namuhla contact nge izinto ezinjalo kubangela izifo ezintsha, ezingamahlalakhona komzimba futhi kuwuphawu lwesimila. Abakhi kubalulekile yabaningi kukho yesimanje indoda izimpahla zivame busuka isakhiwo sabo noma ukuthi mutagen. Kungaba izinwele wemvelo, ukudla, amakhemikhali yasendlini, qeda intuthu, ezimbonini kanye nokunye okuningi. Zonke lezi zinto ngendiza emoyeni, kuthiwa imali emhlabeni futhi zimuncwe yizimila iza ukudla. Ngaphezu kwalokho, mutagens kwemvelo kuthinte nezilwane nezinambuzane, ukushintsha imikhuba yabo, okwenza kakhulu ngobudlova futhi yizifo kalula. Kuyaphawuleka ukuthi kwakungasebenzeki zaphawula ushintsho olunjalo, bayokuya kuzuze emzimbeni.

Ukudla mutagens

Namuhla, imboni yezokudla imvume yokusebenzisa ezinye imikhiqizo unezithako izakhi ummbila, sayinela ukungena kanye oilseeds. Bona ingatholakala Syrups, ufulawa, amafutha, isitashi. Kuyinto lezi elisekela zisetshenziselwa izinto eziningi ezinkulu ukwenziwa imikhiqizo eminingi ezisukela amabhisikidi, ingane ukudla, ayi nososo kokuqeda. Mhlawumbe, okwamanje singayiboni izinguquko zofuzo ibangelwa ukudla okunjalo, kodwa kusobala ukuthi uyozizwa abazukulu bethu. Laboratories emhlabeni wonke bayaqhubeka ukuhlola indlela izilwane zithonywa lezi mutagens. Ucwaningo luye lwabonisa ukuthi ngokuhamba kwesikhathi eba ukungazali, futhi imvamisa yokwanda koshintsho ezizukulwaneni zayo kwandisa kaningi. Futhi uzinake ukuthi kungenzeka mutagens kwakheka ezinye ukudla osekonakele. Ngokwesibonelo, ngo-ayisikhilimu amadala, ibhotela, amaqanda ekhiqizwa compounds ukuguqulelwa i mutagen. Uma inyama iphekwe in juice ayo, njengoba le nqubo ithatha indawo.

izinyathelo zokuvikeleka

Ngemva sezwa ukuthi izwe lethu ligcwele mutagens, umbono wokuthi thina nje buthuntu. Kodwa empeleni, lolu lwazi kusiza kufanele uqaphe ngokwengeziwe lapho ukhetha ukudla. Futhi, ningakwenqabi ezinye izincomo. Ungalokothi udle ukudla osekonakele; phezu contact amagilavu yasendlini yokuhlanza ukusetshenziswa iraba kanye buso; zama senqabe ukudla equkethe colorants NEZIVIKELAKUVUNDA; banciphise ukusetshenziswa amaswidi. Sebenzisa ukupheka ginger, parsley, lwesinaphi, isitshalo seqanda, u-anyanisi, upelepele, cilantro, iklabishi, apula ne-green tea - mikhiqizo ukuthambisa umthelela mutagens.
