Multiple Choice
In eukaryotic cells, the site of ribosomal RNA (rRNA) synthesis is the:
A
Rough endoplasmic reticulum
B
Nucleolus
C
Golgi apparatus
D
Nuclear envelope
Verified step by step guidance1
Understand that ribosomal RNA (rRNA) synthesis is a key process in the production of ribosomes, which are essential for protein synthesis in cells.
Recall that in eukaryotic cells, the nucleolus is a specialized region within the nucleus where rRNA genes are transcribed and ribosome assembly begins.
Recognize that the rough endoplasmic reticulum is involved in protein synthesis but not in rRNA synthesis; it is studded with ribosomes but does not produce rRNA itself.
Note that the Golgi apparatus functions mainly in modifying, sorting, and packaging proteins and lipids, and is not involved in rRNA synthesis.
Understand that the nuclear envelope surrounds the nucleus and controls transport in and out of the nucleus but is not the site of rRNA synthesis.
