Yini i-epigenetics

Igcine ukubuyekezwa ngoFebruwari 16, 2022 ngu Roger Kaufman

Imvelo yomuntu kanye nomhlaba kungashintshwa - Iyini i-epigenetics?

Amaphethini wokuziphatha athile angashintshwa

Umakhi owashona ngo-1988 i-quantum physics kanye nomnqobi weNobel Prize uRichard Feymann wake wathi:
Okokuqala, konke ukubonakaliswa kwento kwenziwa ngezinto ezimbalwa ezifanayo zokwakha, futhi yonke imithetho yemvelo ibuswa imithetho efanayo yemvelo evamile. Lokhu kusebenza kuma-athomu nezinkanyezi kanye nakubantu.

Okwesibili, okwenzeka ezinhlelweni eziphilayo kuwumphumela wezinqubo ezifanayo ezingokwenyama namakhemikhali ezenzeka ezinhlelweni ezingaphili.

Kungenzeka kakhulu ukuthi izinqubo zengqondo kubantu nazo ziyingxenye yalokhu.

Okwesithathu, abukho ubufakazi bokuthuthukiswa okuhleliwe kwezenzakalo zemvelo.

Die ubunkimbinkimbi besimanje bempilo kwavela ngezimo ezilula kakhulu zenqubo engahleliwe yokuzikhethela kwemvelo kanye nokusinda kwento ephilayo evumelana nezimo.

Okwesine yilokhu Universe ezinkulu kakhulu nezindala maqondana nemiqondo yabantu yendawo nesikhathi.

Ngakho-ke mancane amathuba okuthi lokhu kube njalo Universe yadalelwa abantu noma lokhu kuthathwa njengendikimba yayo eyinhloko. Okokugcina, izenzo eziningi zomuntu azizalwanga kodwa ziyafundwa.

Amaphethini okuziphatha athile angashintshwa ngokusebenzisa izindlela ezingokwengqondo, zamakhemikhali, nezomzimba.

Ngakho imvelo yomuntu nomhlaba ngeke kuthathwe njengokungaguquki, kodwa kungashintshwa.

Yini i-epigenetics - hhayi izakhi zofuzo ezisilawulayo - silawula izakhi zethu zofuzo

Enkulumweni yakhe, uProf. Spitz uzokhuluma ngokuhlobana phakathi kwe-epigenetics, izakhi zofuzo kanye nomthelela wemvelo.

Ngeshwa, okutholwe yisayensi ngalezi zihloko maqondana nempilo kanye nokuvimbela kwaziwa kuphela yindilinga encane yososayensi, abelaphi kanye nezinhlangano ezinentshisekelo.

Sisebenza kanzima ukushintsha lokhu!

Inkulumo ihlola umthelela we-epigenetic wezici zemvelo ekuthuthukisweni komuntu kanye nempilo kanye namathuba avela kithi sonke ngenhloso yokuvimbela izifo ezingapheli.

Lokhu kuhlanganisa amathoshi ezihlokweni zikavithamini D kanye nelanga, Ezemidlalo nokuzivocavoca, ukudla okunomsoco kanye ne-microbiota, ama-fatty acids, izici zomphakathi kanye nengqondo yomuntu.

Isiphetho: Umuntu ngokuqinisekile akasona isakhiwo esinesici futhi izakhi zofuzo zinquma kuphela ukuthambekela kwezifo ezithile.

Inkinga ngokuvamile yizici zemvelo ezenziwe ekhaya zomphakathi wethu wezimboni.

Kodwa abakwaziyo lokhu bangazisiza bona nabanye. Sisize futhi usakaze izwi!

Uyilokho okwenzayo: Ukuvivinya umzimba kushintsha kanjani ufuzo lwakho i-cottage shizi

Ezemidlalo ziyawenza umehluko. Kodwa izinsolo zokuthi ukuvivinya umzimba ngisho kunethonya elihle ezakhini zethu zofuzo kusanda kuqhathaniswa. Abacwaningi bakwazile ukukhombisa izinguquko ze-epigenetic ngokusebenzisa ezemidlalo - ezindaweni ezibalulekile emiphumeleni emihle yezempilo yezemidlalo.

Iyini i-epigenetics? - ingabe siyizakhi zofuzo noma imvelo? | SRF Einstein

Isikhathi eside, ososayensi babecabanga ukuthi izici zethu zofuzo kuphela ezilolonga ukukhula kwethu kwezinto eziphilayo.

Kuyacaca manje ukuthi iDNA ayikuchazi konke. Ngisho namawele afana nofuzo awafani futhi athuthuke ngendlela ehlukile.

Ngoba indawo esizungezile nayo inethonya endleleni ufuzo lwethu olubonakala ngayo. "Einstein" ku-epigenetics.

Iyini i-epigenetics? – Ubuciko bokupakisha esitokisini

Amathonya emvelo angathinta okunamathiselwe kwe-methyl kumaprotheni e-histone ama-chromosome.

Lokhu kushintsha izinga lokupakishwa kwe-DNA - futhi lokhu kunquma ukuthi isakhi sofuzo esithile singafundwa noma cha.

Ngale ndlela, indawo ezungezile ingalolonga izici zento ephilayo ezizukulwaneni ngezizukulwane.

UThomas Jenuwein uphenya ukuthi amaqembu e-methyl anamathiselwe kanjani kuma-histones.
