Cell membranes protect and organize cells ... and the proteins that are found in these membranes contain sorting signals, which are like molecular zip codes that specify their final destination.

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 cytoplasm. Tiny pores ...

Researchers create a cleaner and greener bio-based proton exchange membrane for fuel cells made of plant and animal materials ...
