英语使用场景

Then comes anaphase I: the quartet of chromatids are pulled apart so as to form two sets of paired chromatids.

Following the replication of chromosomes, resultant chromatids remain attached at the centromere.

Each chromosome consists of two chromatids held together by the centromere.

Chromatids --- The two parallel strands of chromatin, connected at the centromere, that constitute a chromosome after DNA synthesis.

At this stage, when the chromatids have been separated from each other, they can again be regarded as complete chromosomes.

Often this intertwining leads the chromatids of homologous chromosomes to actually exchange corresponding pieces of DNA, a process called crossing-over or genetic reassortment.

The chromatids, once separated from their twins, can now be called chromosomes.

Once the chromatids are separated they can be called chromosomes.

In diplotene the pairs of chromatids begin to separate from the tetrad formed by the association of homologous chromosomes.
