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. 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.
WebDec 21, 2024 · By the end of S phase, each chromosome has made an exact copy and consists of two sister chromatids. At this point in the cell cycle the sister chromatids are held together tightly at the centromere. While the two sister chromatids are physically joined together they are still considered one replicated chromosome (Figure 2).
