GCSE Biology - Monoclonal Antibodies #40

The video explains monoclonal antibodies, which are antibodies from a single clone of cells. It covers their production, starting with cloning B lymphocytes and combining them with tumor cells to form hybridomas. These hybridomas produce identical antibodies. The video also discusses how animals like mice are used to generate specific antibodies by injecting them with antigens. Monoclonal antibodies can be tailored to bind specific proteins or cells, making them useful in medical applications such as targeting cancer cells with drugs or radioactive materials.

What is the primary function of antibodies in the immune system?

• To bind to foreign materials

• To produce antigens

• To create new white blood cells

• To destroy red blood cells

What is a hybridoma cell?

• A cell that divides slowly

• A type of bacteria

• A cell that produces antigens

• A fusion of a B lymphocyte and a tumor cell

Why are tumor cells used in the production of monoclonal antibodies?

• They produce antigens

• They are resistant to drugs

• They divide rapidly

• They are easy to isolate

How can monoclonal antibodies be used in cancer treatment?

• By binding to healthy cells

• By producing more cancer cells

• By attaching drugs or radioactive materials to target cancer cells

• By increasing the size of tumors

What is a key advantage of monoclonal antibodies?

• They are produced by red blood cells

• They are naturally occurring in the body

• They can bind to multiple antigens

• They always bind to one specific target
