In eukaryotic cells, the membrane that surrounds the nucleus — commonly called the nuclear envelope — partitions this DNA from the cell's protein synthesis machinery, which is located in the ...

Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles ...

But it wasn’t clear how cells translated being squished into relocating. Many of the same researchers, again working in two independent teams, have now found that the nucleus is responsible for ...

as well as the interior of the nucleus. In contrast to organelles with a lipid bilayer membrane, membraneless structures are formed through a process known as liquid-liquid phase separation. When it ...

Amyotrophic lateral sclerosis (ALS) is a relatively rare but very serious disease of the nervous system. A cure is not yet ...

Specialised animal cells have components that allow them to complete a specific purpose. Specialised animal cells include red blood cells, sperm, eggs, nerve cells, muscle cells, ciliated cells ...

However, they still require proteins made from instructions in the cell nucleus to function properly and to assemble multiprotein complexes like the photosynthetic apparatus. Specialized transporters ...

Unlike other cellular sub-structures (for example, the nucleus, mitochondria, and endoplasmic reticulum), the synapse does ...

The nuclei in our cells are miniature ... pepper the dividing membrane, serving as gateways for materials and messages entering and exiting the nucleus. While the basic need for this shuttle ...
