Telomerler: DNA’n\u0131n Koruyucular\u0131<\/h2>\n\n

DNA zincirlerindeki koruyucu ba\u015fl\u0131klar olan telomerler, ya\u015flanmada \u00e7ok \u00f6nemli bir rol oynar. Ara\u015ft\u0131rmac\u0131lar, Scott’\u0131n uzay u\u00e7u\u015fu s\u0131ras\u0131nda telomer uzunlu\u011funda \u015fa\u015f\u0131rt\u0131c\u0131 bir art\u0131\u015f g\u00f6zlemlediler ve bunun uzay ko\u015fullar\u0131n\u0131n t\u00fckenmelerini yava\u015flatm\u0131\u015f olabilece\u011fini \u00f6ne s\u00fcrd\u00fcler. Ancak D\u00fcnya’ya d\u00f6nd\u00fckten sonra telomer k\u0131salmas\u0131 meydana geldi ve bu da ya\u015flanma ve hastal\u0131klarla olas\u0131 ba\u011flant\u0131lar hakk\u0131nda endi\u015felere yol a\u00e7t\u0131.<\/p>\n\n

Gen \u0130fadesi: Yeni S\u0131n\u0131ra Uyum Sa\u011flama<\/h2>\n\n

Uzay u\u00e7u\u015fu ayn\u0131 zamanda gen ifadesini de etkiledi.

Bu de\u011fi\u015fiklikler, v\u00fccudun uzayda uzun s\u00fcreler boyunca uyum sa\u011flamaya devam etti\u011fini g\u00f6steriyor.<\/p>\n\n

Epigenetik: Uyumun Kimyasal \u0130\u015faretleri<\/h2>\n\n

Gen ifadesini d\u00fczenleyen kimyasal i\u015faretleyiciler olan epigenetik modifikasyonlar, hem Scott’ta hem de Mark’ta benzer de\u011fi\u015fiklikler g\u00f6sterdi. Bununla birlikte, Scott’\u0131n genomu, D\u00fcnya’ya d\u00f6nd\u00fckten sonra ba\u015flang\u0131\u00e7 de\u011ferine d\u00f6nen baz\u0131 benzersiz modifikasyonlar sergiledi; bu da v\u00fccudun uzay u\u00e7u\u015fundan sonra iyile\u015fme yetene\u011fini g\u00f6steriyor.<\/p>\n\n
