Final answer:
The translation of mRNA into proteins, a process involving several types of RNA including mRNA, rRNA, and tRNA, occurs at a ribosome within the cell.
Step-by-step explanation:
All the different kinds of RNA are translated in the ribosome. Translation is the process by which the genetic code in messenger RNA (mRNA) is read to synthesize proteins. Three main types of RNA are involved in this process: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). The mRNA, synthesized in the nucleus, carries the genetic instructions from DNA and travels to the ribosome in the cytoplasm, where rRNA helps form the ribosome itself and tRNA brings amino acids to the ribosome to be assembled into proteins.
This complex interplay of different RNA types is fundamental to gene expression and the functioning of all cellular life.
