The DNA sequence determines the protein that is going to be produced. The first step is the transcription where DNA sequence is transcribed to mARN. After the mARN is formed this will go out of the nucleus and into the cytoplasm. In the cytoplasm the mARN, together with the tARN and the ribosome will make a protein by a process called translation. In this process the ARN sequence is read to give and join the amino acids that are required to form the protein.
