yes, but antibodies form complex with antigens and gets destroyed along with the antigens. The memory B cells will be there for any future attack by the similar antigens, so as to produce antibodies again.

in normal cells the size of the nucleus keeps decreasing compared to the size of the cytoplasm as these cells mature.
