Transcription and Translation RNA
... A tRNA is a single RNA chain that is folded into a two dimensional cloverleaf. This then folds in three dimensions to an L-like structure. tRNAs are small RNA molecules (usually in the range of 73 - 93 nucleotides) that participate in the translation of mRNAs. They are not part of the ribosome. But ...
