This question probably a bit outside the course but oh well
Since immunoglobulin is really specific and there are seem to be infinite variety of them inside our body. Hence, according to a bit of my research, are they produced by recombination-activating genes? If so, for the coding message to be read and produce antibodies, the cell must carry synthesis of protein from transcription and translation right? Meaning for 1 gene, we can code for 1 polypeptide = possible many proteins (i.e immunoglobulin in this case) ? The final point I am trying to ask is: when we produce an antibody initially, we don't just produce only 1 big molecule of antibody but many of them from the same type?
Hope this question makes sense, thanks for help!
