The dna codes for the production of messenger rna (mrna during transcription. in eukaryotic cells, the mrna is processed and migrates from the to the messenger rna carries coded information to where this information is translated and used i for protein synthesis.

The correct answer will be-

1. Nucleus

2. Cytosol

3. Ribosome

Explanation:

The synthesis of proteins or gene expression in eukaryotes is complex and is mediated through two processes: transcription and translation.  

The process of transcription transcribes the DNA to mRNA which takes place in the double membrane organelle called Nucleus.  

The process of translation takes place in the cytosol in the organelle called ribosomes which translated the mRNA into proteins. So the mRNA has to move from the nucleus to the cytosol through nuclear pores.

Thus, Nucleus, Cytosol and the Ribosome are the correct answer.
