Which of the following is made in the nucleus and never leaves it? Protein mRNA DNA Ribosomes
Question
Which of the following is made in the nucleus and never leaves it?
- Protein
- mRNA
- DNA
- Ribosomes
Solution
Analysis of Options
-
Protein: Proteins are synthesized in the cytoplasm, primarily on ribosomes, and often undergo post-translational modifications before they perform their functions.
-
mRNA: Messenger RNA (mRNA) is transcribed from DNA in the nucleus but then exits the nucleus to be translated into proteins in the cytoplasm.
-
DNA: DNA resides in the nucleus and contains the genetic instructions; it does not leave the nucleus.
-
Ribosomes: Ribosomes are molecular machines either free in the cytoplasm or attached to the endoplasmic reticulum, and they synthesize proteins, but they are not made in the nucleus.
Conclusion
Based on the analysis above:
- DNA is the correct answer. It is made in the nucleus and does not leave it.
Final Answer: DNA
