Multiple Choice

Genetic recombination frequently occurs in the body’s B cell population. Why is this advantageous to the
immune system?

More genetic diversity in antibody genes creates more diversity in antibodies.

Having the ability to produce more diverse antibodies allows B cells to respond to a larger number of pathogens.

More genetic diversity allows CD8 effector cells to be able to recognize and kill more endogenous pathogens.

A and B.

B and C.

All of the above.

Verified step by step guidance

Understand the role of B cells in the immune system: B cells are responsible for producing antibodies, which are proteins that can specifically bind to antigens (foreign substances) and help neutralize or eliminate them.

Recognize the importance of genetic recombination in B cells: Genetic recombination in B cells leads to the creation of diverse antibody genes, which in turn results in a wide variety of antibodies. This diversity is crucial for the immune system to recognize and respond to a vast array of pathogens.

Evaluate the statement about CD8 effector cells: CD8 effector cells, also known as cytotoxic T cells, are primarily involved in recognizing and killing infected cells. They do not directly benefit from the genetic recombination in B cells, as their function is different from that of B cells.

Analyze the options given: Option A states that genetic diversity in antibody genes creates more diversity in antibodies, which is true. Option B states that diverse antibodies allow B cells to respond to more pathogens, which is also true. Option C incorrectly links genetic recombination in B cells to CD8 effector cells.

Conclude which options are correct: Since options A and B correctly describe the advantages of genetic recombination in B cells, the correct answer is 'A and B.'
