These "minichromosomes," which have telomeres at either end but no centromere, are then amplified many times as the macronucleus matures. Consequently, each macronucleus is estimated to contain ...

Researchers propose a two-step regulatory mechanism for non-Rabl configurations of centromeres in the nucleus. Centromeres are chromosomal domains that link pairs of sister chromatids together during ...

Telomeres are specialized nucleoprotein structures at the ends of eukaryotic chromosomes that are essential for chromosome stability and cellular proliferation. Telomeric DNA does not encode for ...

Notably, chromosomes 1D, 3D, 4D, and 5D were assembled without gaps for the first time, with chromosomes 1D and 5D reaching the telomere-to ... These centromeres are rich in retrotransposons ...
