Which molecule carries the genetic instructions necessary for the synthesis of proteins?

• A. RNA
• B. DNA
• C. ATP
• D. Enzymes

Answer: (B)

The molecule that carries the genetic instructions necessary for the synthesis of proteins is DNA. DNA (deoxyribonucleic acid) contains the sequences known as genes, which encode the information required to assemble specific proteins. This process begins with transcription, where RNA is synthesized based on the sequence of the DNA. The RNA then undergoes translation to produce proteins. Although RNA plays a critical role in transcribing and translating genetic information, it is the DNA that serves as the blueprint, whereas ATP is primarily involved in energy transfer within cells, and enzymes are proteins that catalyze biochemical reactions but do not themselves carry genetic information. Thus, DNA is the fundamental molecule responsible for storing and transmitting the genetic code necessary for protein synthesis.
