Translated: Compared to a chemotherapy drug designed to cause DNA breaks to prevent cell replication, ciprofloxacin produced similar "sister chromatid exchange" counts, which happen when damaged DNA strands need to pull in duplicate material from "sister" strands.
Counting SCEs is also used to measure human DNA mutations from things like carcinogens and radiation.
