In contrast to cohesin, which binds two sister chromatids together, condensin is thought to bind a single chromatid at multiple spots, twisting the chromatin into a variety of coils and loops ...

The chromatids arrive at the either end of each cell and new nuclear membranes form. With meiosis in a female, there is only one dividing cell at this point. As in telophase I, the cytoplasm of ...

You may hear a sentence like, “Chromatids of homologous chromosomes overlap at a point called the chiasma,” and think it ...

Cell division, the basic means by which genetic information is passed from generation to generation, involves tightly coordinated movements of a cell's DNA. This page describes the major phases of ...

As long as they remain attached to each other the two identical copies of the chromosome are known as sister chromatids. The separated sister chromatids are now known as chromosomes. Their DNA ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of ...

The nucleus of a germline stem cell undergoes two divisions, firstly separating homologous chromosomes and secondly separating chromatids. Haploid gametes contain 23 single chromosomes.

Recombination usually occurs between allelic sequences on homologs or between sister chromatids, but can involve non-allelic DNA with high-sequence identity. Such non-allelic homologous recombination ...

Homologous chromosomes segregate in meiosis I, whereas chromatids disjoin in meiosis II. Scientists of the research group Chromosome Biology now revealed how the conserved Hrr25 kinase of yeast ...
