tRNA Structure. Transfer RNA (or abbreviated as tRNA) is small RNA molecule, typically between 70 to 90 nucleotides in length. The primary tRNA function is to deliver amino acids required for the process of protein synthesis. Transfer RNAs are carrying amino acids to the ribosome, where the actual protein synthesis takes place.
Remember, there are 20 different amino acids involved in making our proteins. Proteins can only be made correctly when the amino acids are assembled in the right order. The job of tRNA is to match up the amino acids with the correct codons in the mRNA strand. We can look at our codon chart to get an idea of what tRNA's job is like. Let's see here.
