APAKAH MAKSUD AUXOTROPHY dalam CORSICA?
Auxotrophy
Auxotrophy adalah ketidakupayaan organisma untuk mensintesis sebatian organik tertentu yang diperlukan untuk pertumbuhannya. Auxotroph adalah organisma yang memaparkan sifat ini; auxotrophic adalah kata sifat yang sepadan. Auxotrophy adalah bertentangan dengan prototrofi, yang dicirikan oleh keupayaan untuk mensintesis semua sebatian yang diperlukan untuk pertumbuhan. Kaedah penyaduran replika yang dilaksanakan oleh Esther Lederberg termasuk auxotrops yang sensitif suhu; iaitu kemampuan mereka untuk mensintesis adalah bergantung kepada suhu. Auxotroph berbilang juga boleh wujud bersama pada masa yang sama, dalam organisma yang sama. Dalam genetik, ketegangan dikatakan auksotropik jika ia membawa mutasi yang menyebabkan ia tidak dapat mensintesis sebatian penting. Sebagai contoh, mutant yis dengan gen laluan sintesis uracil yang tidak aktif adalah uracil auxotroph. Ketegangan semacam itu tidak dapat mensintesis uracil dan hanya dapat tumbuh jika uracil dapat diambil dari alam sekitar. Ini adalah bertentangan dengan prototroph uracil, atau dalam hal ini strain jenis liar, yang masih boleh tumbuh tanpa ketiadaan uracil.
Definisi auxotrophy dalam kamus Corsica
Takrif auksotrofi dalam kamus adalah ketidakupayaan untuk mensintesis faktor pertumbuhan tertentu, disebabkan oleh perubahan mutasi.
