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.

kow [346]
<span>The correct answer is cGMP.</span> 
 <span>cGMP, during the dark (when there are no stimulations of photoreceptor cells), reaches high intracellular levels. When the light stimulation occurs cGMP levels decrease because it is converted to GMP by phosphodiesterase. Phosphodiesterase is activated by transducin which is activated by excited rhodopsin (contains photopigment).</span>  
<span>
Low levels of cGMP block the cGMP gated ion channels and that prevents the entry of Na and Ca. Because of that membranes becomes more negative, hyperpolarization occurs and this creates a signal for the next cell.</span>
