Final answer:
Eukaryotic mRNA, tRNA, and ribosomal RNA all undergo specific processing steps and are functionally integrated in the protein synthesis process within the ribosome.
Step-by-step explanation:
Eukaryotic mRNA, tRNA, and ribosomal RNA (rRNA) share several common features that are crucial for their role in the process of protein synthesis. All these RNA species are transcribed from DNA and undergo specific processing steps before they are mature and functional. For example, eukaryotic pre-mRNA is capped with a 5' methylguanosine cap and a poly-A tail and undergoes splicing to remove introns and reconnect exons. Similarly, tRNAs and rRNAs are cleaved from longer RNA molecules and may also experience intramolecular cleavage and methylation. Despite these processing differences, the ultimate role of mRNA, tRNA, and rRNA in the translation process is interlinked within the ribosome. Ribosomes themselves are composed partly of rRNA and act as the site of protein synthesis, during which tRNA brings amino acids to the ribosome and mRNA provides the template that dictates the sequence of the amino acids in a protein.
