Micronucleus Tests - ț̢
Induction and quantitative measurement of chromosomal damage leading to the formation of micronuclei (MICRONUCLEI, CHROMOSOME-DEFECTIVE) in cells which have been exposed to genotoxic agents or IONIZING RADIATION.
Micronucleus, Germline - ț̢
The smaller, reproductive, transcriptionally inert nucleus in the cells of ciliate PROTOZOANS, as distinguished from the larger, vegetative, transcriptionally active MACRONUCLEUS. Micronuclei participate in MEIOSIS and autogamy during GENETIC CONJUGATION.
