After mRNA leaves the nucleus, it travels into the cytoplasm , where it can then be used by ribosomes to make proteins.

Quick Scoop

Once an mRNA molecule is fully processed in the nucleus (capped, spliced, and polyadenylated), it is exported through nuclear pore complexes in the nuclear envelope. These pores act like gated channels that specifically recognize properly processed mRNA bound to export proteins.

In the cytoplasm, mRNA is found in several places where translation and regulation occur. It can float freely in the cytosol, attach to ribosomes on the rough endoplasmic reticulum, or localize to specialized structures like RNA granules that help control when and where proteins are made.

Ultimately, the key path is: nucleus → nuclear pore → cytoplasm (cytosol and/or rough ER) , where the mRNA serves as a template for protein synthesis. Information gathered from public forums or data available on the internet and portrayed here.
