Which molecules are required for translation according to the material?

• A. mRNA, tRNA, Ribosome, Amino Acid
• B. DNA, RNA Polymerase, Helicase, Ligase
• C. mRNA, DNA, Ribosome, ATP
• D. tRNA, DNA, Polymerase, Ribosome

Answer: (A)

Translation uses an mRNA template, tRNA adaptors carrying amino acids, the ribosome as the molecular machine, and the amino acids themselves as the building blocks. The ribosome reads each codon on the mRNA, the matching tRNA brings in the correct amino acid, and peptide bonds form to assemble the growing polypeptide. Energy is used during the process (often via GTP), but the core components required are these four. Other options include DNA and DNA-processing enzymes, which belong to transcription or replication rather than translation, so they don’t fit.
