Citoesqueleto y Núcleo

What is the cytoskeleton?

• A network of lipids

• A network of protein filaments

• An energy-producing organelle

• DNA wrapped in histones

What are the main components of the cytoskeleton?

• Microfilaments, intermediate filaments, and microtubules

• Nucleus, cytoplasm, and membrane

• Ribosomes, mitochondria, and endoplasmic reticulum

• Enzymes, hormones, and carbohydrates

What function does the nuclear lamina serve?

• Transport oxygen

• Anchor and provide stability to the nucleus

• Produce proteins

• Store energy

Which filaments connect to the nuclear lamina?

• Microfilaments

• Intermediate filaments

• Microtubules

• Motor proteins

What happens to the nuclear lamina during mitosis?

• It remains intact

• It disassembles and reforms

• It disappears permanently

• It turns into ribosomes

How do microtubules assist in nuclear positioning?

• With motor proteins like dynein and kinesin

• With actin filaments

• With lipid synthesis

• With ribosomes

What allows mechanical communication of the cytoskeleton?

• Generate ATP

• Transmit external forces to the nucleus

• Synthesize proteins

• Decompose nutrients

What would happen without this cytoskeleton-nuclear membrane connection?

• The cell would be stronger

• The nucleus would lose stability

• DNA would replicate faster

• There would be no mitochondria

What role does the nuclear lamina play in cell division?

• It regulates cell metabolism

• It provides structural support to the nucleus

• It helps in DNA replication

• It facilitates protein synthesis

How do intermediate filaments contribute to cellular integrity?

• By providing elasticity and strength

• By transporting nutrients

• By forming a rigid structure

• By facilitating cell division
