Single anaphase chromosomes (in crane‐fly spermatocytes) moved backwards after double irradiations with an ultraviolet light (UV) microbeam, first of the interzone and then of a kinetochore: the chromosome irradiated at the kinetochore moved backwards rapidly, across the equator and into the other half‐spindle. High irradiation doses at the kinetochore were required to induce backward movement. Single irradiations of kinetochores or interzones were ineffective in inducing backward movements.
