If the proline codon is CCX (X is any base),what is the number of RNA codons that code for the amino acid proline?

Question

Quizplus · Accepted Answer

There are four possible RNA codons that can code for proline, which are CCU, CCC, CCA, and CCG. The "X" in the proline codon CCX represents any base (A, U, C, or G), so there are four possible combinations of CC with any of these bases. Therefore, there are four RNA codons that code for the amino acid proline.

If the Proline Codon Is CCX (X Is Any Base),what
