Question

Which of these is mismatched?

विकल्प

• Post transcriptional control - nucleus

• Translational control - cytoplasm

• Transcriptional control - nucleus

• Post translational control - nucleus

Answer 1

Post translational control - nucleus

Explanation:

In eukaryotes, transcriptional and post-transcriptional controls occur in the nucleus because that is where DNA is stored, and mRNA is first synthesised and processed. Once the mature mRNA moves into the cytoplasm, translational control takes over as ribosomes begin building proteins. Post-translational control involves modifying those finished proteins, adding chemical groups or folding them, which naturally happens in the cytoplasm or organelles like the ER, making the “nucleus” pairing incorrect for this stage.
