Savatey [412]

Answer:

(C) Aminoacyl-tRNA synthetases have an additional active site that binds to non-cognate tRNAs. The tRNAs that bind to this second active are hydrolyzed and released from the enzyme.

Explanation:

In case of translation, proof reading is done by aminoacyl-tRNA synthetases only. Aminoacyl-tRNA synthetases have two mechanisms to avoid error during translation which are mentioned as under:

<u>(1) Chemical proof reading:</u> Incorrect amino acids rather than being hydrolyzed in catalytic pocket get hydrolyzed in editing pocket and thus they hardly get attached to tRNA.  

For example: For distinguishing similar amino acids like isoleucine and valine, isoleucyl-tRNA synthetase uses a second active site which is meant for only valine not for isoleucine. In this particular site, valine which had entered the enzyme is cleaved away with the help of editing reaction after which the enzyme is well prepared to process isoleucine which is the correct amino acid for this enzyme.

<u>(2) Kinetic proof reading: </u>Even if an incorrect amino acid has entered a particular aminoacyl-tRNA synthetase, it does not cause appropriate conformational change in the enzyme because of which the incorrect amino acid loosens from the enzyme and does not get incorporated.

Note: In this example, only chemical proof reading is mentioned not kinetic proof reading.

Beneficios y desventajas de la modificación genetica
finlep [7]
La manipulación genética representa todas aquellas técnicas que permiten modificar de forma directa los genes en el interior de las células de los organismos vivos. Estas modificaciones pueden ser a través de la inserción, la eliminación o la alteración de uno o más genes específicos. Todas las instrucciones que hacen que un organismo sea lo que es están codificadas en los genes, es decir que estos fragmentos de ADN son los que le indican a cada parte de las células y a cada célula en el cuerpo de un organismo multicelular o unicelular, qué debe hacer, cuándo y cómo. La manipulación genética es uno de los procesos científicos biotecnológicos más empleados hoy en día, ya que incluye todas las herramientas necesarias para modificar las características físicas de prácticamente cualquier ser vivo o, mejor dicho, de todo lo que tenga información genética en su interior (ADN o ARN).

Hoy en día la manipulación genética es uno de los temas más discutidos por la sociedad científica, pues existen herramientas biotecnológicas capaces de manipular de manera fácil y efectiva casi cualquier gen que se desee en un organismo Entre los organismos que se pueden “manipular genéticamente” se incluye al ser humano, y es allí donde surgen la mayoría de los debates, ya que a pesar de que la manipulación genética puede ayudar a curar un gran número de enfermedades hereditarias, también puede utilizarse para crear armas biológicas sumamente peligrosas.
