Meiosis -- the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell -- is a major crossroads in all organisms reproducing sexually. Yet, how the cell ...

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. In a study of meiosis in budding yeast, a research team ...

The development of a new organism from the joining of two single cells is a carefully orchestrated endeavor. But even before sperm meets egg, an equally elaborate set of choreographed steps must occur ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

This is a preview. Log in through your library . Abstract Diploid Rhoeo discolor is a complete translocation heterozygote which generally forms a ring or chain of 12 chromosomes in meiosis. The ...

A two-cell embryo of , stained to visualize DNA (red) and the cell membrane (green). One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can ...

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 ...
