The correct Answer is:
**Step-by-Step Solution:** 1. **Understand the Question**: The question asks about what determines the amino acid sequence during protein synthesis. 2. **Identify the Key Term**: The key term in the question is "amino acid sequence" which is crucial for understanding protein synthesis. 3. **Recognize the Role of mRNA**: The messenger RNA (mRNA) is responsible for carrying the genetic information from DNA to the ribosomes, where proteins are synthesized. 4. **Explain mRNA Function**: mRNA is transcribed from DNA by the enzyme RNA polymerase. It contains codons, which are sequences of three nucleotides that correspond to specific amino acids. 5. **Link mRNA to Amino Acids**: The sequence of codons in the mRNA determines the sequence of amino acids in the protein. Each codon specifies a particular amino acid. 6. **Discuss Other RNA Types**: - **tRNA (Transfer RNA)**: It helps in bringing the correct amino acids to the ribosome but does not determine the sequence itself. - **rRNA (Ribosomal RNA)**: It is a component of the ribosome and facilitates the translation process but does not carry the genetic code. 7. **Conclude the Answer**: Since mRNA carries the coded information that dictates the amino acid sequence, the correct answer to the question is mRNA. **Final Answer**: The amino acid sequence in protein synthesis is decided by the sequence of mRNA (messenger RNA). ---
