Nach 10 Minuten Wartezeit wird die Mischung filtriert. Es wird etwas Waschmittel zum Filtrat gegeben und vorsichtig vermischt. Am Ende wird vorsichtig 3 ml sehr kalter Alkohol \u00fcber die Mischung gegeben. Die DNA der Tomate wird sichtbar.<\/p>\n<p style=\"font-weight: 400; text-align: justify;\">Um DNA aus der Mundschleimhaut zu extrahieren, sp\u00fclt man den Mund kr\u00e4ftig mit Salzwasser. Das Wasser kommt dann in ein Reagenzglas, man gibt etwas Waschmittel hinzu und schwenkt vorsichtig. Die Mischung wird mit kaltem Alkohol \u00fcberschichtet und 5 Minuten auf Eis stehen gelassen. Auch hier wird wieder die DNA sichtbar.<\/p>\n<p style=\"font-weight: 400; text-align: justify;\">Auf den Fotos sehen wir einige Arbeitsschritte und auch die Versuchsergebnisse. Einige Sch\u00fclerinnen und Sch\u00fcler konnten die DNA sogar auf ein Holzst\u00e4bchen wickeln.<\/p>\n<p>Eva Jaff\u00e9.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-58385\" src=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-317x423.jpeg?strip=all\" alt=\"\" width=\"263\" height=\"351\" srcset=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-317x423.jpeg?strip=all 317w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-540x720.jpeg?strip=all 540w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-768x1024.jpeg?strip=all 768w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-1152x1536.jpeg?strip=all 1152w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2-320x427.jpeg?strip=all 320w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2.jpeg?strip=all 1440w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-2.jpeg?strip=all&amp;w=864 864w\" sizes=\"(max-width: 263px) 100vw, 263px\" \/> <img decoding=\"async\" class=\"alignnone wp-image-58387\" src=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-317x423.jpeg?strip=all\" alt=\"\" width=\"256\" height=\"342\" srcset=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-317x423.jpeg?strip=all 317w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-540x720.jpeg?strip=all 540w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-768x1024.jpeg?strip=all 768w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-1152x1536.jpeg?strip=all 1152w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-320x427.jpeg?strip=all 320w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image.jpeg?strip=all 1440w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image.jpeg?strip=all&amp;w=864 864w\" sizes=\"(max-width: 256px) 100vw, 256px\" \/><img decoding=\"async\" class=\"alignnone wp-image-58389\" src=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-317x423.jpeg?strip=all\" alt=\"\" width=\"254\" height=\"339\" srcset=\"https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-317x423.jpeg?strip=all 317w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-540x720.jpeg?strip=all 540w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-768x1024.jpeg?strip=all 768w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-1152x1536.jpeg?strip=all 1152w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3-320x427.jpeg?strip=all 320w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3.jpeg?strip=all 1440w, https:\/\/e969z83yjsq.exactdn.com\/wp-content\/uploads\/2022\/12\/Image-3.jpeg?strip=all&amp;w=864 864w\" sizes=\"(max-width: 254px) 100vw, 254px\" \/><\/p>\n<p style=\"font-weight: 400;\">\n","protected":false},"excerpt":{"rendered":"<p>Die Jahrgangsstufe 11 hat in Biologie DNA aus Pflanzenzellen (Tomate) und Tierzellen (Mundschleimhaut) extrahiert.
