Like mRNA, tRNA has a ribose sugar, U instead of T, and is single stranded. Unlike mRNA, which remains a long single strand of nucleotides, tRNA folds so that some areas pair up. The resulting structure has an anticodon on one end and a site for an amino acid to attach on the other end. There is base complementarity (A pairs with U and G pairs with C) between an mRNA codon and tRNA anticodon. If the amino acid serine attaches to a tRNA, which of the following anticodons could be at the opposite end of the tRNA molecule? Select one: a. UCU and UCA b. AGA and AGU c. AGA and AGT d. UCA and ACG
