In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...
A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female ...
Scientists studying zebrafish larvae noticed something weird. Skin cells seemed to be dividing without replicating their DNA. They confirmed that what they were seeing was real, upending what we ...
Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two ...
One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, ...
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 ...
