Syntelic attachment
Syntelic attachment occurs when both sister chromosomes are attached to a single spindle pole. Normal cell division distributes the genome equally between two daughter cells, with each chromosome attaching to an ovoid structure called the spindle. During the division process, errors commonly occur in … See more Microtubules extend from the spindle poles and attach to the first kinetochore they encounter. Because this process is stochastic and not facilitated or directed, the first microtubules to come into contact with a kinetochore … See more Syntelic attachment is not uncommon in early metaphase, and can often be resolved by error correction mechanisms that are well-conserved across metazoans. If syntelic … See more Error correction is closely tied to the spindle assembly checkpoint (SAC), which oversees the progression through mitosis and can halt the cell in metaphase until proper bi-orientation of all chromosomes is achieved. Initial attachments occur randomly, and the … See more • Spindle checkpoint • Kinetochore • Spindle apparatus See more WebJan 1, 2024 · Amphitelic attachment: the two sister kinetochores are attached to microtubules from opposite poles.

Webchore microtubules to the opposite pole (amphitelic attachment; Fig. 1A). However, three types of mis-attachments can occur in early prometaphase: (1) Monotelic attachment (Fig. 1B), in which one sister becomes attached to microtubules from one pole while the other remains unattached; (2) Syntelic attachment (Fig. 1C), WebIt was proposed that delayed centrosome separation promotes syntelic attachment in the vicinity of one pole, which can develop into merotelic attachment by an additional MT approach from the other pole (Figure 5B, part 1). Similar results have been reported after bipolarization of a monopolar spindle .

WebMar 29, 2005 · Attachment by only one kinetochore, monotelic attachment, is typical of early prometaphase, but occasionally, both sisters become attached to the same pole, producing syntelic attachment (figure 2b). Unattached kinetochores have high concentrations of spindle checkpoint proteins, and a single unattached kinetochore is capable of sustaining …
WebSyntelic attachment indicates that both sister kinetochores face the same pole and attach to microtubules emanating from that pole (Figure 1b). By contrast, monotelic attachment describes kinetochores that face opposite poles but only one kinetochore in the pair binds to microtubules ( Figure 1 c). body and tail lettersWebNov 30, 2010 · At a higher magnification, it was readily apparent that one chromosome near the pole displays a clear syntelic attachment in which the kinetochore connects to two … clonazepam eating disorderWebDec 9, 2013 · Bipolar attachment generates tension on chromosomes, but chromosomes become tension-defective when sister-chromatid cohesion is eliminated or when two sister kinetochores are attached by microtubules emanating from the same spindle pole (syntelic attachment).
