If a tRNA molecule has an anticodon which reads CAG, what will it match up with and what amino acid is it carrying?
It is carrying glutamine and will match with a GUC codon on the mRNA.
It is carrying leucine and will match with a GTC codon on the DNA.
It is carrying no amino acid and will match with a UGA codon on the mRNA.
It is carrying valine and will match with a GUC codon on the mRNA.

I've taken this test before and I am 100% sure it's not A. Even though on the codon chart that's where it lines up.

I just checked the codon chart in my textbook (Lehninger Biochemie) and it says that GUC codes for Valine. Here's an RNA codon chart on Wikipedia: it seems to match what I have in my book. http://en.wikipedia.org/wiki/Genetic_code#RNA_codon_table
