[EX Q]: MRNA is made during the first step of protein synthesis, which is transcription. The DNA's genetic information, or secret code, gets written onto a strand of mRNA.

The ribosome figures out where to start on the mRNA by finding a special three letter "begin" sequence called a codon. The ribosome then moves down the strand of mRNA. When the ribosome sees the "stop" code, it ends the translation and the protein is complete.
