Explanation:

Protein synthesis involves transcription (DNA to mRNA in nucleus) and translation (mRNA to protein at ribosome). First, DNA is "unzipped" by RNA polymerase to build mRNA (transcription in nucleus). Then mRNA travels to ribosome (translation site). At ribosome, codons on mRNA are "read", tRNA brings amino acids, peptide bonds form (hemoglobin synthesis begins). When all codons processed, hemoglobin synthesis complete.

Answer:

Top - left box: amino acids released by tRNA form peptide bonds (hemoglobin synthesis complete). Bottom - left box: mRNA travels to a ribosome where its codons will be "read" (hemoglobin synthesis begins). Right - side middle box (below "hemoglobin synthesis begins"): DNA molecule is "unzipped", RNA polymerase is used to build a mRNA molecule (in nucleus).
