Este sistema ha evolucionado para identificar y cortar secuencias de diferentes DNA de virus de DNA evitando la infección. Actualmente existen varias plataformas para el diseño de RNAs guía, aunque también es posible realizarlo de forma manual.

This system has evolved to identify sequences of different DNA viruses and cut them in order to avoid infection. This system is used in vitro for gene edition, relying on the production of double-strand breaks and their subsequent repair. Currently, there are several platforms for the design of the guide RNA, and it is also possible to design it manually. The components of the system can be delivered to the cell through a plasmid or through a ribonucleoprotein.

Bbases will discuss the advantages of this new technique, the ways in which it can be what is exchange rate control, and some of the limitations found in its application. En esta revisión nos centraremos en su función original en procariotas y en cómo los investigadores la han modificado para proporcionar nuevas técnicas de edición de genomas. Figura 1: Fase de adaptación. La imagen no representa exactamente la disposición de los loci.

Figura 2: Fase de inhibición. Cada unidad de crRNA contiene una secuencia guía de tje nucleótidos y una repetición parcial directa, donde la primera dirige a Cas9 a un blanco de 20 nucleótidos a través del apareamiento de bases de Watson-Crick Cas9 en rosado es apuntada al DNA genómico a través de un sgRNA que consiste en una secuencia guía de 20 nucleótidos y una secuencia scaffold.

Cas9 media una ruptura de doble hebra alrededor de 3 pb aguas arriba del PAM. Figura 4: Edición génica inducida por una nucleasa. Primeramente, se debe caracterizar el problema de investigación y a partir de allí seleccionar el gen blanco. Primeramente, es aconsejable buscar dors sgRNA diseñadas anteriormente en bibliotecas comerciales. Se recomienda elegir las secuencias entre los primeros exones, después del codón de inicio Luego de seleccionar math concept functions gen blanco, se procede a diseñar el sgRNA.

Debido a que estos recursos utilizan en sus bases de datos genomas de sus organismos de interés, es importante verificar si el organismo de interés del investigador se encuentra dentro de su base de datos. Si no es posible diseñar el sgRNA con alguno de estos recursos, se debe realizar el diseño de novo. Para ello, hay que seguir una serie de pasos generales, detallados foor el Cuadro how does the bases for dna pair up.
