Preferred Term:

caminata cromosómica

Definition:
Técnica con la cual se puede explorar una región desconocida de un cromosoma. Generalmente se utiliza para aislar un foco de interés para el cual no existe una sonda disponible, pero del cual se sabe que está ligado a un gen que ha sido identificado y clonado. Se selecciona un fragmento que contenga un gen conocido y se utiliza como sonda para identificar otros fragmentos superpuestos que contienen el mismo gen. Posteriormente se pueden caracterizar las secuencias de nucleótidos de estos segmentos. Este proceso continúa en toda la longitud del cromosoma.
