WebThe chromosomal aberration test is designed to evaluate the potential of a test compound to induce structural chromosomal abnormalities, such as breaks and exchanges. Chromosomal Aberration Test Procedure WebThe abnormalities that result are termed “chromosome aberrations” and may be visualized at mitosis when cells divide. The frequency of chromosome aberrations increases with radiation dose to the cells and serves as an indicator of radiation dose received, i.e., a biological dosimeter. spicers private collectionWeb【文档描述】 1、第二十二章染色体畸变畸变（chromosome aberrations）第一节断裂愈合和交换学说（breakage-reunion hypothesis）重建（restitution）（三体（trisomy），2n+1）（1）21-三体即Down氏综合征;（2）18-三体，即Edward综合征;（3）13-三体，即Patau综合征;双三体（double trisomy）,2n+1+1。 spicers retreats head office
