which of the following statements about B cells/antibody production is true?
a)each individual B cell can make different classes of antibodies with one specifically
b)each individual B cells is programmed to make antibodies with one specific specificity only
c) each individual B cells is programmed to make antibodies with different specificites
d) each individual B cells is programmed to make different classes of antibiodies with different specificities
e) A AND B are correct
Homework Answers
answer) b)each individual B cells is programmed to make antibodies with one specific specificity only.
Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a memory B cell is activated by antigen , it proliferates and differentiates into an antibody secreting effector cell.
Memory B cells are specific for specific antigen and when activated by that antigen , it produces soecific antibodies to that antigen.

Which of the following statements is correct about the production of antibodies after stimulation of B cells by antigen? Multiple Choice a. Later, under the influence of T-helper cells, IgM-secreting plasma cells may stop producing and secreting IgM in favor of another antibody class, usually IgD. b. Pentameric IgM serves as the B-cell receptor for antigen, and monomeric IgM is the first type of antibody secreted after B-cell activation. c. Class switching occurs when a cell secreting IgM changes the...

Which of the following is a correct about how lymphocytes in the Adaptive Immune System acquire millions of possible combinations of antibodies? Vertebrate genomes have millions of different antibody genes, which are constantly being transcribed and translated. After differentiation, a small number of immunoglobin genes in each lymphocyte undergo internal recombination to create a unique antibody for each B-cell or T-cell. RNA interference cleaves viral nucleotide sequences, then uses them as a template to produce special antibodies that can target...
