Detailed explanation-1: -Final answer: RNA could be found in both the nucleus and the cytoplasm.
Detailed explanation-2: -Transport of messenger RNA (mRNA) from the nucleus to the cytoplasm is an essential step of eukaryotic gene expression.
Detailed explanation-3: -Whereas many proteins are selectively transported from the cytoplasm into the nucleus, most RNAs are exported from the nucleus to the cytoplasm. Since proteins are synthesized in the cytoplasm, the export of mRNAs, rRNAs, and tRNAs is a critical step in gene expression in eukaryotic cells.
Detailed explanation-4: -Both RNA and ribosomes could be found in both the nucleus and the cytoplasm.
Detailed explanation-5: -mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide.
