chro·ma·tid

 (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.

Background: DNA replication and sister chromatid cohesion 1 (DSCC1) (also called DCC1) is a component of an alternative replication factor C complex that loads proliferating cell nuclear antigen onto DNA during S phase of the cell cycle.
Interestingly, there were two GO categories with AUC>0.9, including cell cycle checkpoint (AUC=0.91648), and mitotic sister chromatid segregation (AUC=0.91597).
They can be formed from eccentric chromosomes, chromatid fragments, whole chromosomes, or chromatids that lag behind in anaphase and are left outside the daughter nuclei in telophase.
Sister chromatid exchange (SCE) analysis is a method that allows the physical quantification of exchanged genetic material between sister chromatids during in vitro mitosis.
Sibling chromatid exchange (SCE) is among the cytogenetic markers used most commonly in determining the early biologic effects of agents that lead to DNA damage (2, 8).
Although studies evaluating the genotoxicity of exposure to volatile anaesthetics have shown increased formation of chromosomal aberrations, micronuclei and sister chromatid exchanges (SCEs), in vitro and clinical studies evaluating the genotoxicity and mutagenicity of sevoflurane show conflicting results (2-7).
A recently published paper noted that embryo derived from reciprocal aneuploid oocyte (untimely sister chromatid division during meiosis I, revealed after polar body biopsy) resulted in the birth of a healthy child after correct chromatid segregation during meiosis II [33].
