INCORPORATION OF $sup 3$H-ARGININE IN CHROMOSOMES OF VICIA FABA
Technical Report
·
OSTI ID:4026233
Tritiated arginine was used in an effort to label the nuclear protein of Vicia faba root meristem cells. Previous to labeling, the root tips were treated for 24 hr with 5-aminouracil in order to synchronize cell divisions and obtain a large proportion of mitotic figures. Autoradiographs of chromosomes from the first and second division after labeling were examined. Almost 100% of the chromosomes in the first division were labeled. The marked absence of label in metaphase chromosomes at second division suggests turnover of a major fraction of nuclear protein during one DNA replication cycle. (auth)
