Nako ea liketsahalo tsa nako ea nako e bolela nako ea sebele eo motho a phetseng ka eona. Ka mantsoe a mang, palo ea matsatsi, likhoeli kapa lilemo tseo motho a phetseng ka tsona ha li fetohe , ho sa tsotellehe hore na bophelo ba bophelo bo botle - esita le bo nang le mekhoa e metle ea ho ikoetlisa le ea phepo e nepahetseng - ba phela.
E mong le e mong ea lilemo li fapaneng le tekanyo. Batho ba bang ba bonahala eka ba tsofala ka potlako, ha ba bang ba utloa botsofali ka nako e khutšoanyane.

Phapang pakeng tsa nako ea nako le ea likokoana-hloko
Joaloka batho, re na le lilemo tse peli tse fapaneng: tatellano ea liketsahalo. Mehla ea liketsahalo ke nako ea motho ea phetseng, ha nako ea likokoana-hloko e bua ka hore na motho o lilemo li kae. Mehleng ea likokoana-hloko, hape e bitsoa mehla ea bophelo, e nahanisisa ka mekhoa e mengata ea bophelo, ho akarelletsa le lijo, boikoetliso le mekhoa ea boroko, ho bolela ba seng bakae.
Hore na re lilemo li kae ho feta taolo ea rona. E susumelitsoe ka ho khetheha ke liphatsa tsa lefutso, empa lipatlisiso tsa morao-rao li fana ka leseli la hore botsofali bo ka ameha joang ka lintho tse ka ntle, tse kenyelletsang ho ja, ho ikoetlisa, khatello ea maikutlo le ho tsuba. Litsebi tse ngata tsa litsebi tsa thuto ea bongaka li lumela hore nako ea liketsahalo tsa nako ea liketsahalo ha e phethehe kaha ha e nahane ka mekhoa ena e ka ntle.
Kamoo Bophelo ba Likokoana-hloko bo Fihlileng kateng
Lipatlisiso li bontša hore li-telomeres le methylation ea DNA li bapala likarolo tse kholo botsofaling.
Telomeres ke li-nucleotides lipheletsong tsa li-chromosome. Ba boloka liphello tsa li-chromosome hore li se ke tsa senyeha le ho fapana le chromosome e haufi. Ha e le hantle, li-telomere li laela hore na lisele tsa nako e kae li fela joang ebe lia shoa.
Bo-rasaense ba fumane hore nako ea motho ea holimo ea liketsahalo, e khutšoanyane ea li-telomere.
Phuputso e 'ngoe e fumane hore batho ba nang le li-telomere tse khutšoanyane ba ne ba ka' na ba shoa hang-hang kapa ba hlaheloa ke boloetse kapa boloetse bo bakoang ke lefu lena. Phuputso e 'ngoe e bontša hore ho boloka bophelo bo botle bo ka ntlafatsa botsofali ka ho lelefatsa li-telomere, litaba tse molemo bakeng sa setso sa rona sa mehleng ea khale.
Bo-rasaense ba boetse ba sebelisa DNA methylation ho fumana nako ea likokoana-hloko. Lisele li sebelisa methylation ea DNA ho laola liphatsa tsa lefutso. Ka mantsoe a mang, DNA methylation e fetola liphatsa tsa lefutso. Le hoja morero o nepahetseng oa methylation ha o tsejoe, ke habohlokoa ho nts'etsopele ea embrone, genomic imprinting, botsitso ea chromosome le ho feta.
Phuputso e 'ngoe e ile ea leka ho fumana hore na DNA methylation ke tsela e nepahetseng ea ho bolela nako ea lilemo ka ho bokella mefuta e 8 000 ea mefuta e 51 ea liphatsa le lisele. Boholo ba lisele le lisele tse ithutoang li na le nako e lekanang le ea liketsahalo. Ba bang ha baa ka ba etsa joalo. Phuputso eo e fumane hore likarolo tse ling tsa 'mele li potlakile ho feta tse ling. Ka mohlala, lisele tsa matsoele ke tse ling tsa lisele tsa khale ka ho fetisisa 'meleng. Phuputso e fumane hore esita le lihlahisoa tsa matsoele tse phetseng hantle li ka ba lilemo tse tharo ho feta tse ling tsa 'mele oa mosali. Haeba lihlahisoa tsa matsoele tse phetseng hantle li le haufi le lisele tsa kankere, ke ka karolelano ea lilemo tse 12 tse fetang .
Haeba u thahasella ho hlahloba lilemo tsa likokoana-hloko ka ho eketsehileng, ithute ka RealAge , mohloli o babatsehang oa nako e telele.
