Question
Which of the following is found in the nucleus? a. Ribosome b. Centrosome c. Vacuole d. Nucleolus
Correct Answer
Option D is the correct answer.
Detailed Explanation
The nucleolus is a distinct, dense structure found inside the nucleus of eukaryotic cells. It is the site of ribosomal RNA (rRNA) synthesis and ribosome subunit assembly. Ribosomes are found in the cytoplasm or on the RER, centrosomes are near the nucleus, and vacuoles are in the cytoplasm.
Hint
This is the 'little nucleus' inside the nucleus, where ribosome parts are made.
