Front

What is nuclear division?

Back

Nuclear division is the process by which a cell divides its nucleus, resulting in two nuclei. The most common type of nuclear division is mitosis.

Front

What are enzymes made of?

Back

Enzymes are biological catalysts made of polypeptides (proteins) that speed up chemical reactions in living organisms.

Front

What type of transport does not require energy?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy (ATP). Examples include diffusion and osmosis.

Front

What is the capsid of a virus?

Back

The capsid is the protein shell of a virus that encases its genetic material and is similar to the cell membrane of a cell.

Front

What is the function of surface proteins on a virus?

Back

Surface proteins on a virus recognize and bind to host cells, allowing the virus to enter and infect the host.

Front

Define mitosis.

Back

Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent nucleus.

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase, mitosis, and cytokinesis.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, relying on concentration gradients.

Front

What are polypeptides?

Back

Polypeptides are chains of amino acids that make up proteins, which play various roles in biological processes.

Front

What is the role of the plasma membrane?

Back

The plasma membrane is a biological membrane that separates and protects the interior of the cell from the external environment.
