2023年8月3日 · Chiasmata (singular: chiasma, from the Greek, meaning “X-shaped cross”) is the point of contact that occurs in the Prophase I pachytene phase and links two non-sister …

In genetics, a chiasma (pl.: chiasmata) is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange …

At the end of prophase I, the pairs are held together only at chiasmata (Figure 1) and are called tetrads because the four sister chromatids of each pair of homologous chromosomes are now …

chiasma (pl., chiasmata): Point of physical exchange of equal segments of adjacent nonsister chromatids during the bivalent stage of meiosis.

Chiasmata are X-shaped points of attachment between two non-sister chromatids of a homologous pair. Chiasmata form as a result of crossing over and hence non-sister …

Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks …

2011年3月10日 · Chiasmata prevent the bipolar attachment of sister chromatids in mrc1 mutant cells but not in moa1 mutant cells. We next examined the pre-anaphase centromere dynamics …

2022年9月16日 · Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where …

Chiasmata are the physical manifestations of the process known as crossing over, which occurs during the prophase I stage of meiosis. They are the points where two homologous …

Chiasmata are the points where homologous chromosomes exchange genetic material during meiosis, specifically during prophase I. This process, known as crossing over, results in …
