RNA Polymerase hits stop code and releases the mRNA.

To conclude:-In the first step of transcription, RNA Polymerase binds to DNA and
unwinds it. Then, the RNA Polymerase binds to promoter region of DNA. In the third step, RNA Polymerase reads DNA and creates mRNA.
After this, RNA Polymerase hits stop code and releases the mRNA. At the end, mRNA leaves nucleus and enters the cytoplasm.
-In the first step of translation, rRNA forms Ribosome. In the second step, mRNA binds to ribosome and is read. After this, tRNA proof reads mRNA and transfers amino acids. Then, Amino Acids, attached to the tRNA, attach to the Peptide Bond. Lastly, Ribosomes hits stop codon and completes the protein
end.
