Cell Structure and Function

What is the main function of the nuclear envelope?

• Facilitates DNA replication
• Promotes protein synthesis
• Supports cell division
• Separates nucleus from cytoplasm

What is the significance of the nucleolus in actively dividing cells?

• Disappears completely
• Reduces in size
• Becomes inactive
• Increases in size and number

What is the function of the nucleolus in protein synthesis?

• Translates mRNA
• Replicates DNA
• Modifies proteins
• Produces ribosomal subunits

What is the role of the nuclear envelope in protecting genetic material?

• Enhances protein synthesis
• Promotes cell division
• Stores energy reserves
• Separates nucleus from cytoplasm

What is the function of the nuclear pore complex?

• Replicates DNA
• Synthesizes lipids
• Breaks down waste
• Regulates molecular traffic
