| "In one of
her seminal contributions Barbara McClintock
describes the mechanism leading to the
formation of ring/deleted chromosomes in
maize and the aberrant mitotic behaviour
leading to 'variable mutant
characteristics'. This mechanism, a break
within the centromere together with a break
in either the long or the short arm,
creating a small ring, has been called
"centromere misdivision"; these authors
propose that this be referred to as "the
McClintock mechanism". McClintock also
describes pachytene configurations in
microsporocytes, showing that although the
normal, deleted and ring chromosomes may
synapse, the ring is also seen with the
centromeric region attached to a
non-homologous bivalent." (cited from Mantzouratou et al., Molecular Cytogenetics 2009, 2:3) |

by chromosomal origin for sSMC formed by pseudo-McClintock mechanism However, it turned out that similar to McClintock mechanism with ring chromosome formation, there are cases which seem to evolve by a related mechnaism, called pseudo-McClintock mechansim. |
