    In this sense of correspond, I was alluding to how a sequence of nucleic
    acids (either RNA or DNA) maps to a sequence of amino acids in a protein or
    peptide.

    It's been a while since I last read Steele's book and URL's, so I'm hesitant
    in getting too in depth without brushing up on the particulars, but the
    general jist of the reason I thought the views he put forth were confined to
    the immune system is because the antibodies in the selected lymphocytes
    (with rearranged and hypermutated immunoglobulin genes differing from the
    configuration of these genes in the germ-line) probably more directly
    correspond (or map) to the information contained within the hypothetical
    retrovector shuttles (as a nucleic acid sequence somehow picked up by the
    retrovirus within the lymphocyte).

    I think the nervous system would represent a problem, because as far as I
    know, there isn't an adaptively significant difference in genetic
    configuration between the germ line and individual mature neurons and there
    would be a problem of how behavioral states gained during a lifetime would
    correspond (or map) to retrovector transported information which would cross
    the germ-soma boundary. It seems more feasible in lymphocytes for the
    adaptive state of a lymphocyte producing specific antibodies to possibly
    influence the germline than for the adaptive state in neurons (or neural
    aggregates) to do so, though this doesn't mean Steele's views are correct
    even when confined to the immune system.
