The first step in making a new polypeptide chain is to transcribe or copy the information or roadmap contained in DNA to messenger RNA (mRNA). Drag the labels onto the flowchart to correctly rank the order of events of transcription. All labels will be used.

- The instructions contained in a gene are transcribed as an mRNA molecule.
- DNA in the cell nucleus unwinds
- mRNA detaches from the DNA
- mRNA leaves the cell nucleus and arrives in the cytoplasm
