Each chromosome is, at this time, actually two identical copies. Each copy is called a chromatid. A spindle begins to form from the centrioles. This spindle is made of fibers. The centrioles begin ...

Each replicated chromosome is made up of two identical strands called chromatids that are joined together. Each chromatid is a full length DNA molecule. The stages outlined in the following ...

During meiosis, sister chromatids produced by chromosome duplication are held ... manner that correlates with the loss of sister-chromatid cohesion. Figure 1: Regulation of sister-chromatid ...

Since sister chromatids are identical to each other, recombination with a sister chromatid is expected, in most cases ... For example, when homologs recombine, loss of heterozygosity (LOH) can result, ...

The centromere, a specialized region of the chromosome, serves as a recruitment platform for diverse proteins crucial for maintaining sister chromatid cohesion and for the assembly of kinetochores.
