Solution
The correct option is D Cytoplasm-exon splicing of eukaryotic pre-mRNA
Transcriptional repression plays an important role in gene regulation. In this, the gene expression is controlled by inhibiting the synthesis of mRNA by repressing transcription of particular gene. Post-translational modification is a process by which primary transcript RNA is converted into mature RNA to synthesize protein. Phosphorylation is a very common post-translational modification. Other mechanisms include glycosylation, sulfation, etc. Exon splicing of eukaryotic pre-mRNA takes place in the nucleus. After exon splicing, the mature mRNA then moves to the cytoplasm for protein synthesis. Enhancer is a short region of DNA that binds to activator and increases the rate of transcription of particular gene.Thus, the correct answer is option C.
