Weboocytes. We defined bivalents that had an inter-KT distance exceeding 70% of its maximum as stretched bivalents. These measurements demonstrated that from 2 to 4 hr after NEBD, hereafter referred to as the stretching phase, 92.0% ± 6.7% of bivalents stretched and the stretched state was maintained until the onset of anaphase I (Figure 1B). A bivalent is one pair of chromosomes (sister chromatids) in a tetrad. A tetrad is the association of a pair of homologous chromosomes (4 sister chromatids) physically held together by at least one DNA crossover. This physical attachment allows for alignment and segregation of the homologous chromosomes in … See more The formation of a bivalent occurs during the first division of meiosis (in the zygotene stage of meiotic prophase 1). In most organisms, each replicated chromosome (composed of two identical sister chromatids ) … See more A bivalent is the association of two replicated homologous chromosomes having exchanged DNA strand in at least one site called chiasmata. Each bivalent contains a … See more At the meiotic metaphase I, the cytoskeleton puts the bivalents under tension by pulling each homolog in opposite direction … See more
WebThe other kinetochore pair of the bivalent will establish microtubule connections with the other pole and some studies suggest bivalents have a geometry predisposing them to such biorientation (Sakuno, Tada, & Watanabe, 2009). In addition to providing docking sites for microtubules, the kinetochore also creates an important platform for a ...
