Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...
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 ...
A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell's nucleus, researchers suggest ...
In a multicellular organism, normal growth requires control of cell division to generate cells that are similar to or different from their parents. Analysis of this process in plant roots reveals how ...
When we talk about memories in biology, we tend to focus on the brain and the storage of information in neurons. But there are lots of other memories that persist within our cells. Cells remember ...
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 ...

It might look like a comet or a shooting star, but this time-lapse video is actually a tiny plant root, not much thicker than a human hair, magnified hundreds of times as it grows under the microscope ...
CAMBRIDGE, MA -- Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to ...
Time-lapse footage of a threadlike Arabidopsis root as it grows. Each fluorescent blue dot marks the nucleus of a cell that’s in the process of dividing to produce new cells, which will go on to form ...
