Final answer:
The bases that can achieve the given transformation are U (uracil), C (cytosine), A (adenine), and G (guanine). RNA molecules are composed of nucleotides that contain one of these four bases. The sequence of these bases determines the genetic code in RNA.
Step-by-step explanation:
The bases that can achieve the given transformation are U (uracil), C (cytosine), A (adenine), and G (guanine).
RNA molecules are composed of nucleotides that contain one of these four bases. The sequence of these bases determines the genetic code in RNA. For example, the sequence UCCAGU in the given transformation corresponds to the amino acid sequence Serine-Arginine in a protein.
