Codes are present on:
Correct answer: A. mRNA
- A. mRNA
- B. rRNA
- C. tRNA
- D. None of the above
Explanation
In the context of molecular biology and genetics, "codes" typically refer to codons. Codons are sequences of three nucleotides (triplets) found on mRNA molecules. These codons serve as the genetic code that specifies particular amino acids during protein synthesis. Each codon corresponds to a specific amino acid or a start or stop signal.
