Abstract
The dynamics of heat-shock puff activity and cell nuclei electrophoretic mobility in the larvae salivary glands of normal and temperature-sensitive mutant stocks of Drosophila melanogaster after heat shock (37 degrees C) were studied. The parallel changes of these characters and interlinear differences affected by ts mutation were found. Positive correlation between heat shock puff size and cell nuclei electrophoretic mobility was detected.
摘要
研究了黑腹果蝇正常品系和温度敏感突变品系幼虫唾液腺在热休克（37摄氏度）后热休克胀泡活性和细胞核电泳迁移率的动态变化。发现了这些特征的平行变化以及受温度敏感突变影响的品系间差异。检测到热休克胀泡大小与细胞核电泳迁移率之间存在正相关。
