Endoplasmic Reticulum
D
Nucleolus
Verified step by step guidance
1
Understand the role of ribosomes: Ribosomes are essential for protein synthesis in the cell, translating mRNA into polypeptide chains.
Identify the location of ribosomal assembly: Ribosomal assembly begins in the nucleolus, a region within the nucleus where ribosomal RNA (rRNA) is synthesized and combined with ribosomal proteins.
Explore the function of the nucleolus: The nucleolus is responsible for producing and assembling ribosome components, including rRNA and ribosomal proteins, which are then transported to the cytoplasm.
Differentiate between the nucleolus and other cell organelles: The Golgi apparatus, cytoplasm, and endoplasmic reticulum have different functions, such as protein modification, transport, and lipid synthesis, but do not assemble ribosomes.
Conclude with the correct location: Based on the synthesis and initial assembly of ribosomal components, the nucleolus is the correct answer for where ribosomal assembly occurs.
