Ribonucleic acid (RNA) can be found in both the nucleus and the cytoplasm of eukaryotic cells.
-
In the nucleus, RNA is involved in various processes including transcription, where messenger RNA (mRNA) is synthesized from DNA, as well as the processing of precursor mRNA and the assembly of ribosomal RNA (rRNA) and other types of RNA.
-
In the cytoplasm, RNA plays a critical role in translation, where mRNA is translated into proteins, and other types of RNA, such as transfer RNA (tRNA) and ribosomal RNA (rRNA), function in the protein synthesis machinery.
Therefore, the correct answer is in the nucleus & in the cytoplasm.
