mRNA does not enter the nucleus. It is transcribed from DNA inside the nucleus and then exits the nucleus to carry genetic information to the ribosomes in the cytoplasm for protein synthesis.
The genetic code is transferred from the nucleus into the cytoplasm by RNA. RNA is used to duplicate the DNA so it doesn't have to leave the nucleus.
Basically, mRNA carries a message away from the nucleus. The nucleus says hey, we need these proteins made, and mRNA is made by using RNA polymerase to copy the information on DNA. That mRNA then moves out of the nucleus to a ribosome, where rRNA and tRNA will interact with the mRNA, eventually resulting in the production of a fully functional protein.
mRNA is transported out of the nucleus through nuclear pores in a process called mRNA export. Once in the cytoplasm, the mRNA binds to ribosomes where protein synthesis occurs.
After exiting the nucleus, mRNA travels to the ribosomes in the cytoplasm where it is used as a template for protein synthesis.
Messenger RNA, or mRNA, is transcribed from DNA in the nucleus of the cell. It is then transported to the cytoplasm.
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.

The nucleus.
In the nucleus of the cell. If the cell lacks a nucleus, then the mRNA is immediately translated without additional processing.The transcription takes place inside the nucleus. The new mRNA is then spliced and afterwards leaves the nucleus.
By the nuclear pores that stud the double walled membrane. These check points are tasked with, for instance, checking mRNA quality as it leaves the nucleus.

Information
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
Transfer of mRNA from the nucleus to the cytosol occurs through nuclear pores. These large protein complexes in the nuclear envelope allow selective passage of molecules, including mRNA, between the nucleus and cytoplasm. mRNA is exported in a process facilitated by nuclear export receptors and generally occurs after mRNA processing is completed in the nucleus.
