WebThe transport of mRNA molecules from the nucleus of the cell to the cytoplasm is essential for protein synthesis. The mRNA molecule is moved through the nuclear pores by molecular motors, and once in the cytoplasm, it binds to a ribosome and is ready for translation. tRNA molecules, on the other hand, are not usually transported from the nucleus.
