Descriptor English: Sister Chromatid Exchange
Descriptor Spanish: Intercambio de Cromátides Hermanas
Descriptor intercambio de cromátides hermanas
Scope note: Intercambio de segmentos entre cromátides hermanas de un cromosoma, bien entre las cromátides hermanas de una tétrada meiótica o entre las cromátides de un cromosoma somático duplicado. Su frecuencia aumenta por las radiaciones ultravioleta e ionizante y por otros agentes mutagénicos y es especialmente alta en el SÍNDROME DE BLOOM.
