Núcleo (biología)

The video tutorial explains the role of the nucleus in eukaryotic cells. It describes the nucleus as a membrane-bound structure that contains most of the cell's genetic material. The nucleus is responsible for regulating gene expression and is often referred to as the cell's control center.

What is the nucleus primarily described as in the context of biology?

• A membrane-bound structure within eukaryotic cells

• A type of protein found in the cell

• A free-floating organelle in prokaryotic cells

• A lipid molecule in the cell membrane

Where is most of the genetic material found within a eukaryotic cell?

• In the cytoplasm

• In the mitochondria

• In the cell membrane

• In the nucleus

What is one of the key functions of the nucleus?

• Digesting cellular waste

• Producing energy

• Transporting nutrients

• Regulating gene expression

How is the nucleus often referred to in terms of its function?

• The energy powerhouse

• The digestive system

• The cell control center

• The transport hub

Which of the following is NOT a function of the nucleus?

• Producing proteins

• Acting as the cell control center

• Containing genetic material

• Regulating gene expression
