codón de inicio
Scope note: Codón que dirige el inicio de la traducción de proteínas (TRADUCCIÓN GENÉTICA) al estimular la unión del ARNt iniciador (ARN DE TRANSFERENCIA MET). En procariotas, los codones AUG o GUG pueden actuar como iniciadores, mientras que en los eucariotas AUG es el único codón iniciador.
