Which component is NOT involved in protein synthesis?

Which component is NOT involved in protein synthesis?

• A. Amino acids
• B. DNA
• C. mRNA
• D. Ribosomes

Answer: (B)

In the process of protein synthesis, DNA plays a fundamental role as the genetic blueprint but does not directly participate in the translation of that information into protein. Instead, it serves as a template for the synthesis of mRNA during transcription. The mRNA then carries the necessary code from the DNA in the nucleus to the ribosomes in the cytoplasm, where ribosomes help assemble amino acids into proteins, based on the sequence dictated by the mRNA. Thus, while DNA is crucial for providing the information necessary for building proteins, it is not itself involved in the active process of protein synthesis, which primarily occurs through mRNA, ribosomes, and amino acids.
