[Ultrastructure study on the whole chromosome in radiation induced anomalies: II. Re-arrangements and fragments].
Chromosome aberrations induced by 500 rads gamma ray irradiation (dicentrics, rings, and fragments) were observed at the ultrastructural level using the "whole mount" technique. The area of chromatid rejoining could not be demonstrated. The pairing of fragments observed could be explained by the perisistence of interchromatid fibers.
