Definition of chromatid in English:

chromatid

noun ˈkrəʊmətɪdˈkroʊməˌtɪd

Biology

Each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
〔生〕染色单体
Example sentencesExamples
- There a somatic genetic principle was established whereby mitotic chromosome replication produces sister chromatids that are different from one another.
- Any bias in the segregation of one or the other of a pair of homologous chromosomes or chromatids between the oocyte and the polar body can have a dramatic effect on the genetic makeup of a population.
- The rate at which heterozygosity is lost depends on the extent to which chromosomes and chromatids segregate randomly during anaphase.
- One is the nonreciprocal transfer of information of both DNA strands of a donor chromatid to a chromatid of the homologous chromosome.
- A double crossover involving one linear chromatid and both chromatids of the circular chromosome generates a linear trimer.

Origin

Early 20th century: from Greek khrōma, khrōmat- 'colour' + -id².
