WebAnaphase: the chromatids are separated from each other andmoved by the cytoskeleton to opposite ends of the cell. This cre-ates two identical bundles of chromosomes in the cell.

WebThe tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned precisely with each other (Figure 1). The synaptonemal complex supports the exchange of chromosomal segments between non-sister homologous chromatids, a process called crossing over.
Web(1) The chromatids do not appear replicated. Instead, homologous chromosome pair, and then replicate (2) Crossing over between parts of homologous chromatids occurs at … WebWhen fully compact, the pairs of identically packed chromosomes are bound to each other by cohesin proteins. The connection between the sister chromatids is closest in a region called the centromere. The conjoined sister chromatids, with a diameter of about 1 µm, are visible under a light microscope.
WebEach copy of the chromosome is referred to as a sister chromatid and is physically bound to the other copy. The centromere is the structure that attaches one sister chromatid to another. Because a human cell has 46 chromosomes, during this phase, there are 92 chromatids (46 × 2) in the cell.
