Meiosis, the process by which haploid products are created from diploid precursors, is central to sexual reproduction. Meiosis can be thought of as a modified mitotic division with notable ...

Meiosis is a specialized type of cell division in which two rounds of chromosome segregation follow a single round of DNA replication. In diploid organisms, meiosis generates gametes with a haploid ...

The chromatids (now also considered chromosomes) arrive at the opposite ends of the cell, and new nuclear membranes form. Mitosis, which describes only the division of the nucleus, is now complete. As ...

Germ cell fate decisions are poorly understood, despite their central role in reproduction. One fundamental question has been whether germ cells are regulated to enter the meiotic cell cycle (i.e., ...

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 ...

The authors present convincing data to validate abscisic acid-induced dimerisation to induce a synthetic spindle assembly checkpoint (SAC) arrest that will be of particular importance to analyse ...

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 ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...
