The 3' end of the tRNA is single-stranded, and it carries the amino acid. This is because the amino acid attaches to the 3' hydroxyl group (-OH) of the ribose sugar at the 3' end of the tRNA molecule. The 5' end of the tRNA is also single-stranded, but it carries the phosphate group and the 5'-triphosphate cap. The anticodon recognition site is located in the loop of the tRNA molecule that connects the two strands of the RNA double helix.
