  • Term: chromatid
  • Gramatical category: s
  • Definition: One of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.
  • Context: The spindle checkpoint detects improper kinetochore-microtubule attachments and translates these defects into biochemical activities that inhibit the anaphase-promoting complex or cyclosome (APC/C) throughout the cell to delay anaphase onset. A deficient spindle checkpoint leads to premature sister-chromatid separation and aneuploidy.
