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 ...

The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell ...

Embark on an exciting journey to uncover the wonders of cell division as we explore mitosis and meiosis. In this captivating explanation, we'll delve into how cells divide and pass on genetic ...

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 ...

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 ...

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 ...

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., ...

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, ...

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 ...
