MRNA is also called messenger RNA. It has codons that are a sequence of three nucleotides. Each codon carries the message specifying a certain amino acid. The tRNA has anticodons that are complementary to the codon on the mRNA. The anticodons aid the tRNA in determining the sequence of amino acid that the mRNA codon has specified. Thus the correct answer is option 'C'.

Explanation:
Sequence Determination:
- The amino acid sequence in protein synthesis is determined by the sequence of mRNA (messenger RNA).
Role of mRNA:
- mRNA carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.
- The sequence of nucleotides in mRNA determines the sequence of amino acids in the protein being synthesized.
Transcription and Translation:
- During transcription, a complementary mRNA strand is synthesized from a specific gene in the DNA.
- This mRNA strand contains codons, which are three-nucleotide sequences that code for specific amino acids.
- During translation, tRNA (transfer RNA) molecules bring the corresponding amino acids to the ribosome based on the mRNA codons.
- The sequence of amino acids brought by tRNA molecules is determined by the sequence of nucleotides in the mRNA.
Importance of cDNA:
- cDNA (complementary DNA) is synthesized from mRNA and can be used to determine the amino acid sequence in protein synthesis.
- cDNA lacks introns found in genomic DNA, making it a more direct representation of the mRNA sequence.
Therefore, the sequence of amino acids in protein synthesis is ultimately determined by the sequence of mRNA, which carries the genetic information from the DNA to the ribosomes for translation into proteins.
