S\u0151t, k\u00f6nnyen lehet, hogy a marsi \u00e9let ut\u00e1ni kutat\u00e1sban is.<\/p>\n\n\n

Az Astrobiology c\u00edm\u0171 foly\u00f3iratban k\u00f6zz\u00e9tett publik\u00e1ci\u00f3 szerint a kutat\u00f3k azt tal\u00e1lt\u00e1k, hogy a bazaltl\u00e1va-\u00fcveg fel\u00fclet\u00e9n spont\u00e1n k\u00e9pz\u0151d\u00f6tt ribonukleinsav, vagyis RNS, ami az \u00e9let kialakul\u00e1s\u00e1hoz sz\u00fcks\u00e9ges els\u0151 genetikai anyag lehetett. Ilyen bazaltl\u00e1va-\u00fcvegb\u0151l rengeteg volt a F\u00f6ld\u00f6n 4,35 milli\u00e1rd \u00e9vvel ezel\u0151tt, \u00e9s a mai napig sok van a Mars felsz\u00edn\u00e9n is.<\/p>\n\n\n\n

Steven Benner, az Alkalmazott Molekul\u00e1ris Evol\u00faci\u00f3 Alap\u00edtv\u00e1ny (Foundation for Applied Molecular Evolution) tud\u00f3sa, a publik\u00e1ci\u00f3 t\u00e1rsszerz\u0151je szerint az elm\u00falt \u00e9vekben a kutat\u00f3k t\u00f6bb elm\u00e9lettel is el\u0151\u00e1lltak, \u00e1m egyik sem adott v\u00e1laszt arra, mik\u00e9nt keletkezhetett az \u00e9let a F\u00f6ld\u00f6n. Emiatt az alap\u00edtv\u00e1ny kutat\u00f3i egy \u00faj megk\u00f6zel\u00edt\u00e9st alkalmaztak.<\/p>\n\n\n\n

Az Elisa Biondi \u00e1ltal vezetett kutat\u00f3csoport \u00fagy tal\u00e1lta, hogy hossz\u00fa 100-200 nukleotidot tartalmaz\u00f3 RNS-molekul\u00e1k keletkeztek, amikor nukleozid-trifoszf\u00e1tok \u00e1tsziv\u00e1rogtak a bazalt\u00fcvegen.<\/p>\n\n\n\n

A szakemberek szerint a F\u00f6ld\u00f6n 4,35 milli\u00e1rd \u00e9vvel ezel\u0151tt rengeteg bazalt\u00fcveg volt a folyamatos becsap\u00f3d\u00e1soknak, valamint a vulk\u00e1nok aktivit\u00e1s\u00e1nak k\u00f6sz\u00f6nhet\u0151en. Emellett a becsap\u00f3d\u00e1sokkal nikkel \u00e9rkezett a F\u00f6ldre, valamint olyan k\u00f6rnyezetet teremtettek, ami ide\u00e1lis lehetett az RNS-k\u00e9pz\u0151d\u00e9s sz\u00e1m\u00e1ra.<\/p>\n\n\n\n

Benner szerint van m\u00e9g n\u00e9h\u00e1ny k\u00e9rd\u00e9s, ami nem tiszt\u00e1zott, p\u00e9ld\u00e1ul, hogy az \u00f6sszes RNS \u00e9p\u00edt\u0151elem hogyan \u00f6lt\u00f6tt ugyanolyan alakot.<\/p>\n\n\n\n

A mostani felfedez\u00e9s viszont fontos, mert a Marson m\u00e9g mindig megtal\u00e1lhat\u00f3k a felsz\u00ednen a 4 milli\u00e1rd \u00e9vvel ezel\u0151tt keletkezett k\u0151zetek. Mindez egy l\u00e9p\u00e9ssel el\u0151r\u00e9bb viheti a kutat\u00f3kat a marsi \u00e9let ut\u00e1ni kutat\u00e1sban is.<\/p>\n\n\n\n
