C) Protein synthesis is the process through which cells read DNA and build the molecular components of new cells.
Explanation:
DNA is the genetic material of the organisms. It stores the genetic information used to make the molecules and other components required for the new cells. This process of formation of molecules is called protein synthesis. During protein synthesis, The DNA forms a complementary messenger RNA (mRNA) in the nucleus of a cell. Synthesis of mRNA from DNA is called transcription. The mRNA released into the cytoplasm where codons on mRNA sequence translate into a polypeptide or protein molecules by linking a chain of amino acids by peptide bonds.
