Indalo yomntu kunye nehlabathi linokutshintshwa- Yintoni i-epigenetics?

Iindlela zokuziphatha ezithile zinokutshintshwa

Umyili wezakhiwo owasweleka ngo-1988 i-quantum physics kunye nophumelele iBhaso leNobel uRichard Feymann wakha wathi:
Okokuqala, zonke iimbonakaliso zento zenziwe ngeebhloko ezimbalwa ezifanayo zokwakha, kwaye yonke imithetho yendalo ilawulwa yimithetho yendalo efanayo. Oku kusebenza kwiiathom neenkwenkwezi kwakunye nasebantwini.

Okwesibini, okwenzekayo kwiinkqubo eziphilayo kusisiphumo senkqubo efanayo yomzimba neyemichiza eyenzeka kwiinkqubo ezingaphiliyo.

Kunokwenzeka kakhulu ukuba iinkqubo zengqondo ebantwini nazo ziyinxalenye yale nto.

Okwesithathu, abukho ubungqina bophuhliso olucwangcisiweyo lweziganeko zendalo.

Die ukuntsonkotha kwangoku kobomi yavela kwiimeko ezilula kakhulu zenkqubo engakhethiyo yokhetho lwendalo kunye nokusinda kwezinto eziphilayo eziguquguqukayo.

Eyesine yile Ehlabathini inkulu kakhulu kwaye indala ngokunxulumene neengcinga zomntu zendawo kunye nexesha.

Ke ngoko akunakwenzeka ukuba Ehlabathini yenzelwe abantu okanye le ithathwa njengomxholo wayo ophambili. Okokugqibela, iindlela ezininzi zokuziphatha zomntu azizalwanga kodwa ziyafundwa.

Iipateni ezithile zokuziphatha zinokutshintshwa ngeendlela zengqondo, iikhemikhali kunye nezomzimba.

Ke indalo yomntu kunye nehlabathi ayinakuthathwa njengento engenakuguqulwa, kodwa inokuguqulwa.

Yintoni i-epigenetics - hayi imfuza elawulayo - silawula imfuza yethu

Kwintetho yakhe, uProf Spitz uya kujongana noqhagamshelwano phakathi kwe-epigenetics, i-genetics kunye neempembelelo zendalo.

Ngelishwa, iziphumo zenzululwazi kwezi zihloko ngokumalunga nempilo kunye nokuthintela ziyaziwa kuphela kwisangqa esincinci sezazinzulu, oogqirha kunye namaqela anomdla.

Sisebenza nzima ukuyitshintsha le nto!

Intetho ihlola impembelelo ye-epigenetic yezinto ezisingqongileyo ekuphuhlisweni komntu kunye nempilo kunye namathuba avela kuthi sonke ngenjongo yokuthintela izifo ezingapheliyo.

Oku kubandakanya izibane kwizihloko ze-vitamin D kunye nelanga, umdlalo kunye nokuzivocavoca, ukondla kunye ne-microbiota, i-fatty acids, izinto zentlalo kunye nengqondo yomntu.

Ukuqukumbela: Ngokuqinisekileyo umntu akalolwakhiwo oluneziphene kwaye imfuza imisela kuphela utyekelo lwezifo ezithile.

Ingxaki idla ngokuba ziimeko ezizezasekhaya zokusingqongileyo kuluntu lwethu lwezoshishino.

Kodwa abo bayaziyo le nto banokuzinceda bona nabanye. Sincede usasaze ilizwi!

Imidlalo yenza umahluko. Kodwa ukurhanelwa ukuba umthambo ude ube nempembelelo entle kwimizila yemfuza yinto entsha. Abaphandi baye bakwazi ukubonisa utshintsho lwe-epigenetic ngokusebenzisa imidlalo - kwiindawo ezibalulekileyo kwimiphumo emihle yempilo yezemidlalo.

Yintoni i-epigenetics? – ingaba sizimfuza okanye sisingqongileyo? | SRF Einstein

Kangangexesha elide, izazinzulu zazicinga ukuba izinto zethu zelifa kuphela zibumba ukukhula kwethu kwebhayoloji.

Ngoku kucacile ukuba i-DNA ayichazi yonke into. Nkqu namawele afanayo ngokwemfuza akaze afane akhule ngokwahlukileyo.

Kuba indawo esihlala kuyo nayo inempembelelo kwindlela imizila yethu yemfuza ebonakala ngayo. "Einstein" malunga ne-epigenetics.

Yintoni i-epigenetics? -Ukupakisha ubugcisa kwiseli

Iimpembelelo zokusingqongileyo zinokuchaphazela i-attachment ye-methyl kwiiprotheni ze-histone ze-chromosomes.

Oku kutshintsha iqondo lokupakishwa kwe-DNA - kwaye oku kugqiba ukuba imfuza ethile inokufundwa okanye hayi.

Ngale ndlela, okusingqongileyo kunokubumba iimpawu zento ephilayo kwizizukulwana ngezizukulwana.

UThomas Jenuwein uphanda ukuba amaqela e-methyl aqhotyoshelwe kwii-histones.
