Which Molecule Remains in the Nucleus During Protein Synthesis

Question

Which molecule remains in the nucleus during protein synthesis?
A) DNA
B) tRNA
C) mRNA
D) rRNA

Accepted Answer

DNA remains in the nucleus during protein synthesis. mRNA is transcribed from the DNA in the nucleus and then moves to the cytoplasm where the actual protein synthesis takes place on ribosomes. tRNA and rRNA also participate in protein synthesis but none of these molecules remain in the nucleus during this process.
