A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

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 ...

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the ...

Most cells in the tissues of most organisms proliferate through somatic cell division (mitosis). This is a continuous cycle where a single cell doubles its genetic information (chromosomes) and ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

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 ...

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine ...
