Manzanas, papas y salmón.

from Cienciaes.com

Josefina Cano da voz a un artículo escrito por Steve Savage, científico agrícola, aparecido en Genetic Literacy Project, en el que el investigador describe nuevas variantes de manzanas, patatas y salmones que han sido modificadas genéticamente. Estas variedades son más resistentes a la degradación, a las plagas y contienen mejoradas sus propiedades alimenticias, razón por la cual las autoridades sanitarias en Estados Unidos y en otros países han aprobado su comercialización. Las manzanas obtenidas se mantienen frescas mucho tiempo después de ser cortadas, gracias a la inactivación del gen que genera la enzima que les produce un color negruzco en poco tiempo debido a la oxidación por el contacto con el aire. Las patatas han sido modificadas de forma que contienen una cantidad reducida de asparagina, un aminoácido que durante el proceso de fritura se puede convertir en acrilamida, un posible agente cancerígeno. Y, por último, a los salmones se les ha introducido un gen que le permite crecer más rápido y con un requerimiento menor de alimento que las variedades salvajes.
