In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two ...

Researchers have clarified how homologous chromosome pairing -- a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

DLGAP5 is proposed as a causal gene related to oocyte meiosis disorder for the first time. It expanded the current spectrum of pathogenic genes responsible for the phenotype of oocyte maturation and ...

In our cells, our DNA carries chemical or 'epigenetic' marks that decide how genes will be used in different tissues. Yet in the group of specialised ...

These ten sex chromosomes pair with each other in a head-to-tail manner and form a chain during meiosis when sperm cells develop. The genetic makeup and the evolution process of such a complex and ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

A research collaboration based in Kumamoto University (Japan) has clarified how homologous chromosome pairing--a process necessary for sperm and egg formation where paternally- and maternally-derived ...
