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 ...

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 ...

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 ...

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, ...

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 ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...
