Solution
The correct option is C RNA synthesis and protein synthesis are coupled
RNA synthesis occurs in the nucleus, but translation occurs on ribosomes in the cytoplasm. Transcription and translation are spatially and temporally separated in eukaryotic cells. Many genes are interrupted by noncoding DNA sequences and hence, mRNA is often extensively modified before translation to remove the noncoding part. Eukaryotes produce mostly monocistronic mRNAs and polycistronic mRNAs are very rare.
