Answer:C) the sequence of nucleotides in the DNA template

Explanation: During protein synthesis, the nucleotide sequence of a DNA molecule is first copied into a nucleotide sequence of an mRNA molecule, and this takes place in the nucleus. The synthesized mRNA is complementary to the DNA. A DNA has four bases: Adenine, Guanine, Cytosine and Thymine while in mRNA Thymine is replaced by Uracil. The mRNA molecule produced from the DNA is transported to the ribosome where protein synthesis takes place. In the ribosome the nucleotide sequence of the mRNA is then read three nucleotides (codon) at a time to code for amino acids. The amino acid sequence of a protein is determined by the nucleotide sequence of an mRNA and its DNA.
