When found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base. When found as the second base in a codon, the third is always interchangeable. For example, UCU, UCC, UCA and UCG are all serine, regardless of the third base.hen found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base.
