WEBMar 25, 2019 · The primary function of sister chromatids is to pass on a complete set of chromosomes to all the daughter cells formed as a result of cell division. During mitosis, they are attached to each other through the centromere – a stretch of DNA that forms protein complexes.

Sister chromatids - Wikipedia
https://en.wikipedia.org/wiki/Sister_chromatids
WEBA sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad.

WEBJan 23, 2019 · By. Regina Bailey. Updated on January 23, 2019. Definition: Sister chromatids are two identical copies of a single replicated chromosome that are connected by a centromere. Chromosome replication takes place during interphase of the cell cycle.

WEBThe two copies of a chromosome are called sister chromatids. The sister chromatids are identical to one another and are attached to each other by proteins called cohesins . The attachment between sister chromatids is tightest at the centromere , a region of DNA that is important for their separation during later stages of cell division.

WEBThis cell is in interphase (late G 2 phase) and has already copied its DNA, so the chromosomes in the nucleus each consist of two connected copies, called sister chromatids. You can’t see the chromosomes very clearly at this point, because they are still in their long, stringy, decondensed form.
