| Early in meiosis, each pair of homologs comes together to form a tetrad containing two pairs of sister chromatids. |
|
| Double reduction is a phenomenon that two sister chromatids of a chromosome sort into the same gamete. |
|
| During meiosis I, the replicated sister chromatids pair with their homologs but segregate as a single unit. |
|
| Changes in chromosome numbers are often caused by errors in separation of sister chromatids during mitosis. |
|
| Precise and timely segregation of sister chromatids during cell division is essential for early embryo development. |
|
| Kinetochores mediate microtubule chromosome attachment and ensure accurate segregation of sister chromatids. |
|
| Thus, the establishment of cohesion between sister chromatids appears to be regulated, directly or indirectly, by a specific acetyltransferase. |
|
| The correct segregation of sister chromatids to daughter cells during mitosis depends on the formation of a bipolar spindle composed primarily of microtubules. |
|
| The centromere is the primary constriction site of eukaryotic chromosomes where sister chromatids appear most tightly paired. |
|
| Separation of human sister chromatids involves the removal of DNA embracing cohesin ring complexes. |
|
| There a somatic genetic principle was established whereby mitotic chromosome replication produces sister chromatids that are different from one another. |
|
| The centromere is the part of a chromosome that links sister chromatids. |
|
| Sister chromatids are copies of the chromatids that become visible during cell division. |
