A micronucleus is a small nucleus that forms whenever a chromosome or a fragment of a chromosome is not incorporated into one of the daughter nuclei during...

The latter is generated from the micronucleus by amplification of the genome and heavy editing. The micronucleus passes its genetic material to offspring...

There is a chance of more than one micronucleus forming when more genetic damage has happened. The micronucleus test is used as a tool for genotoxicity...

maintains two distinct nuclear genomes, the micronucleus and the macronucleus. The macronucleus and micronucleus are located in the same cytoplasm, however...

The two cells exchange a micronucleus. The cells then separate. The micronuclei in each cell fuse, forming a diploid micronucleus. Mitosis occurs three times...
