在后期双著绿点染色体将形成一个桥，无著绿点染色体单体形成一断片，此两者均可记录下来。
At anaphase the dicentric chromatid will form a bridge and the acentric a fragment, both of which can be scored.
结果：经太空诱变后的生物工程细胞染色体畸变率为：环状占10.5%，无着丝断片占36.75%，三射、四射体占13%。
Result: The abnormal chromosome rate of bio-engineering cells muted by outer space were: ring chromosome, 10.5%; acenericfragment, 36.75%; triceneric and fourcentric, 13%.
分析结果进一步肯定了断片率、微核率可以作为测定细胞染色体辐射效应的一个可靠指标。
The results give a further confirmation that the chromosome fragment rate and mini-nucleus rate could be used as a reliable index to determine the effects of irradiation on chromosomes in cells.
