Explanation;
Molecules produced in the nucleus are transported to the cytoplasm via endoplasmic reticulum.
-Endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. It works closely with the Golgi apparatus, ribosomes, mRNA, and tRNA.
