In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

Chromosome segregation is a fundamental process that is necessary for the propagation of all organisms. In meiosis there is a unique form of chromosome segregation in which sister chromatids ...

The chromatids arrive at the either end of each cell and new nuclear membranes form. With meiosis in a female, there is only one dividing cell at this point. As in telophase I, the cytoplasm of the ...

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 activity on this page was designed by science education experts to explain and visualise the three stages of mitosis. By interacting with the activity, you'll see the mitosis phases and ...

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, ...
