Explica el impacto del desarrollo de las técnicas moleculares en los sistemas de clasificación de los organismos.
docker41 [41]

Answer:

Las técnicas moleculares, especialmente aquellas basadas en la manipulación del material genético, permitieron automatizar el proceso de identificación y clasificación de especies

Explanation:

Las técnicas moleculares usadas para la clasificación de organismos son aquellas principalmente relacionadas a la manipulación de su material genético. En especial, las técnicas de extracción de ADN, amplificación mediante la reacción en cadena de la polimerasa (PCR) y posterior secuenciación han posibilitado automatizar el proceso de clasificación de organismos. Los marcadores moleculares de ADN basados en secuencias génicas evolutivamente conservadas tales como, por ejemplo, la secuencia del gen Citocromo Oxidasa I (COI) en animales, son ampliamente usados para automatizar este proceso de identificación y clasificación de nuevas especies.
