APAKAH MAKSUD PROTOTROPHIC 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 prototrophic dalam kamus Corsica
Takrif prototrofik dalam kamus adalah memberi makan semata-mata mengenai perkara bukan organik. Takrif prototropik lain tidak mempunyai keperluan pemakanan tertentu.

Yeast Gene Analysis: Yeast Gene Analysis
Deletions are being created either by replacement of the target gene with
suitable prototrophic markers such as LE U2, HIS3, URA3, and TRP1 (Rothstein,
1983, 1991), or with a dominant kanamycin resistance marker (see also Chapter
5).

Life: The Science of Biology
When different auxotrophic (mutant) strains of bacteria are grown together, do
new prototrophic (wild-type) bacteria appear? Conclusion: The prototrophic
colonies growing on minimal medium could have arisen only by genetic
recombination.

Yeasts in Natural and Artificial Habitats
In mass matings, hybrids between auxotrophic strains can be readily isolated by
plating on selective (minimal) media. Zygotes obtained by mating of prototrophic
strains can be isolated by micromanipulation and grown into diploid cultures.
