 (krō′mə-tĭd)
n.
Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes.

chromatid

(ˈkrəʊmətɪd)
n
(Genetics) either of the two strands into which a chromosome divides during mitosis. They separate to form daughter chromosomes at anaphase

chro•ma•tid

(ˈkroʊ mə tɪd)

n.
either of two identical chromosomal strands into which a chromosome splits before cell division.
[1900; < Greek chrōmat- (see chromatin) + -id1]

chro·ma·tid

(krō′mə-tĭd)
Either of the two strands formed when a chromosome duplicates itself during cell division. The chromatids are joined together by a single centromere and later separate to become individual chromosomes. See more at meiosis, mitosis.

Induction of sister chromatid exchanges and chromosome aberrations in vivo in Etroplus suratensis (Bloch) following exposure to organophosphorus pesticides.
Examples of lethal aberrations to the cell are the dicentric and ring (which are chromosome aberrations) and the anaphase bridge (a chromatid aberration).
Sex chromosome loss, micronuclei, sister chromatid exchange and aging: a study including 16 centenarians.
This sister chromatid cohesion resists the pulling forces of the mitotic spindle and thereby enables the bi-orientation and subsequent symmetrical segregation of chromosomes.
The other mechanism, homologous repair, involves an undamaged DNA molecule that will be used as a template (the DNA of the sister chromatid or the other chromosome).
Short term tests include acute toxicity, sister chromatid analysis, gross chromosomal changes, formation of micronuclei and effects on DNA.

Scientists from Japan, Europe, and the US discuss the history of mitosis research and the model systems that have played a key role; how threads are produced through chromosome condensation; how sister chromatids attach to each other and to the spindle apparatus; how the spindle microtubules nucleate, elongate, pause, and shrink; how kinetochores and centrosomes serve as anchor and control points; the biochemical elements that coordinate the main regulatory stages of entry into mitosis, sister chromatid separation, and mitotic exit; how cells can mis-segregate and unbalance the genome; the cellular changes that occur during cytokinesis; and the differences between mitosis and meiosis.
It happens during DNA replication and uses sister chromatid as a template to repair the DNA double-strand break (21).
