The codon UUU in an mRNA molecule which results in phenylalanine being inserted as the protein is made. Which will be a characteristic of this codon? a. The tRNA molecule that binds to the UUU codon must have an AAA anticodon. Nde ba e2? b. UUU could code for both phenylalanine and alanine during translation. c. The aminoacyl-tRNA synthetase for phenylalanine binds only the UUU codon. d. UUU is probably only one of several codons that code for phenylalanine.
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 lysine attaches to a tRNA, which of the following anticodons could be at the opposite end of the tRNA molecule? a. UUU and UUC b. AAA and AAG c. AGA and AGU d. UCU and UCA
