Answer:When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis.

Answer:

  • New protein synthesis begins in the nucleus, where ribosomes receive instructions to begin the process. Transcription occurs when sections of DNA (genes) encoding a specific protein are copied over to messenger RNA (mRNA) strands.
