Protein synthesis begins with the uncoiling of DNA in the nucleus (step 3), and then mRNA is produced based on the DNA sequence (step 1). The mRNA then moves out of the nucleus to the ribosome (step 6). At the ribosome, the mRNA is read by the ribosome and tRNA molecules bring amino acids to the ribosome (step 5). The ribosome then links the amino acids together, forming a polypeptide (step 4). Finally, the ribosome moves along the mRNA to continue the synthesis process (step 2). Hence, the correct order of protein synthesis is 3, 1, 6, 5, 4, 2, which is represented by option A.
