Conocimientos

 

Masa requerida del ADN del inserto [g] = masa de ADN del vector [g] × {longitud del ADN del inserto / longitud del ADN del vector} × relación molar deseada entre inserto y vector

Notas: La relación deseada es una de este conjunto {1, 2, 3, 5 ,7}

La longitud del inserto debe ser más pequeña que la longitud del vector

Más información

En primer lugar, el ADN del inserto y el vector se digiere mediante endonucleasas de restricción para crear fragmentos de ADN con extremos salientes (o romos). A continuación, los fragmentos de ADN deseados se aíslan y se unen posteriormente mediante tratamiento con ADN ligasa. Por último, el vector intacto resultante se transforma en células E. coli competentes, y los transformantes se identifican mediante métodos de selección genética adecuados.
