Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse ...

Sometimes the best way to understand a biological process is to disrupt the normal process and analyze the result. That’s why Sloan Kettering Institute (SKI) researchers used a strain of mutant mice ...

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 ...

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, ...

Where would we be without meiosis and recombination? A new article describes how proteins called SUMO and ubiquitin and molecular machines called proteasomes play a crucial role in DNA recombination ...

Meiosis is a highly coordinated cell division, which generates four haploid reproductive cells required for sexual reproduction. Meiosis involves one round of DNA replication and two nuclear divisions ...

Scientists at the Sloan Kettering Institute have solved the puzzle of how small chromosomes ensure that they aren’t skipped over during meiosis, the process that makes sperm and egg. From avocado ...

With significant funding from the National Institutes of Health (NIH), a researcher at The University of Texas at Arlington is investigating fundamental biological processes that lead to fertility ...

Researchers from Johns Hopkins University and the University of Copenhagen analyzed over 139,000 embryos and identified variants in key meiosis genes, such as SMC1B, that influence chromosomal ...

Meiosis (pronounced /maɪˈoʊsɨs/ ( listen)) is a special type of cell division necessary for sexual reproduction. The cells produced by meiosis are gametes or ...
