Genetic recombination frequently occurs in the body’s B cell population. Why is this advantageous to the immune system?
A
More genetic diversity in antibody genes creates more diversity in antibodies.
B
Having the ability to produce more diverse antibodies allows B cells to respond to a larger number of pathogens.
C
More genetic diversity allows CD8 effector cells to be able to recognize and kill more endogenous pathogens.
D
A and B.
E
B and C.
F
All of the above.
Verified step by step guidance1
Understand the role of B cells in the immune system: B cells are responsible for producing antibodies, which are crucial for identifying and neutralizing pathogens such as bacteria and viruses.
Recognize the process of genetic recombination: This process occurs in B cells and involves the rearrangement of gene segments to create diverse antibody genes. This diversity is essential for the immune system to recognize a wide array of antigens.
Evaluate the advantages of genetic diversity in antibodies: More genetic diversity in antibody genes leads to a greater variety of antibodies, enabling the immune system to respond to a larger number of different pathogens effectively.
Consider the role of CD8 effector cells: These cells are primarily involved in recognizing and killing infected cells, particularly those infected by viruses. Genetic diversity in antibodies does not directly enhance the function of CD8 cells.
Conclude which options are correct: Since genetic recombination in B cells enhances antibody diversity and the ability to respond to various pathogens, options A and B are correct. Option C is not directly related to the benefits of genetic recombination in B cells.
