In eukaryotic cell architecture, what is the main function of the nucleus?
A
To modify, sort, and package proteins for secretion
B
To store and protect the cell’s DNA and regulate gene expression
C
To synthesize proteins by translating mRNA into polypeptides
D
To produce ATP through oxidative phosphorylation
Verified step by step guidance1
Identify the primary role of the nucleus in eukaryotic cells by recalling its key functions related to genetic material.
Understand that the nucleus houses the cell's DNA, which contains the instructions for all cellular activities.
Recognize that the nucleus protects this DNA from damage and controls access to it, ensuring proper gene regulation.
Note that gene expression regulation involves controlling which genes are turned on or off, influencing protein synthesis indirectly.
Differentiate the nucleus's function from other organelles: protein modification occurs in the Golgi apparatus, protein synthesis happens at ribosomes, and ATP production takes place in mitochondria.
