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 ...

Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...

The breakdown of the nuclear membrane is an essential step for spindle assembly. Because the centrosomes are located outside the nucleus in animal cells, the microtubules of the developing spindle ...

Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found in both animal and plant cells. All life on ...

A series of nanopillars allows for the temporary opening of the nuclear membrane of cells. This process guarantees intervention without degrading their external structure. The nucleus of a cell ...

The researchers found that many of the nerve cells had breaks in the membrane that separates the nucleus from the rest of the cell. This barrier, known as the nuclear envelope, protects and ...

some of the defining characteristics of modern eukaryotic cells—the nucleus, mitochondria, cytoskeleton, cell membrane, and chloroplasts, among others—made their debut. These occurred between the ...

As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 ...

Siegfried Musser, Ph.D., and his team in the Department of Cell Biology and Genetics ... move through the pores of the double-membrane enveloping the nucleus quickly and efficiently without ...

"These changes make the apical membrane—the top of the cell—less stiff and certain constituents of the tight junctions more mobile, without however affecting the barrier formed by these ...
