For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

During meiosis, sister chromatids produced by chromosome duplication are held together by Rec8, a meiosis-specific cohesion protein. Rec8 joins the whole length of the sister chromatids together, and, ...

Meiosis is essential to sexual reproduction. For almost 15 years, it has been commonly held that retinoic acid, a molecule derived from vitamin A, triggers meiosis in mammalian germ cells. Yet new ...

During meiosis, homologous chromosomes are sorted into pairs and are then intimately aligned, or synapsed, along their lengths while a proteinaceous structure, the synaptonemal complex, is assembled ...

During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange parts of their DNA in a process called meiotic recombination. In order to mediate this exchange of genetic material, ...
