Ribosomes are synthesized in which of the following locations?
A
Nuclear Pore Complex
B
Nuclear Lamina
C
Nucleolus
D
Cytoplasm
Verified step by step guidance1
Understand the function of ribosomes: Ribosomes are the cellular structures responsible for protein synthesis. They are composed of ribosomal RNA (rRNA) and proteins.
Identify the site of ribosome synthesis: Ribosomes are synthesized in the nucleolus, a dense region within the nucleus of eukaryotic cells.
Learn about the nucleolus: The nucleolus is the site where rRNA is transcribed and combined with ribosomal proteins to form the subunits of ribosomes.
Differentiate between synthesis and assembly: While ribosomal subunits are synthesized in the nucleolus, they are assembled into functional ribosomes in the cytoplasm.
Review the options: Among the given options, the nucleolus is the correct location for ribosome synthesis, as the other options (Nuclear Pore Complex, Nuclear Lamina, Cytoplasm) do not serve this function.
