The T-cell receptor (TCR) genes (alpha, beta, delta, and gamma) are comprised of numerous, discontinuous coding segments that somatically rearrange to produce heterodimeric cell surface T-cell receptors, either alpha/beta (90%-95% of T cells) or gamma/delta (5%-10% of T cells).
In this case, syntelic arrangement (sister kinetochores attached to microtubules emanating from the same spindle) was studied. Timelapse analysis of mitosis was performed on Drosophila S2 cells stably expressing CID-mCherry for visualisation of the centromeres, and GFP-a-tubulin for the microtubules.
