    please, could someone tell me, is a mismatched base considered a mutation, some or all of the time. somebody kind of confused me on this, they were answering my question through email but Im confused about this one thing

    It is a mutation, but it can still be repaired by the mismatch machinery if the abnormal base pairing is still present (before DNA replication).

    I understand you cant see which cells have mutations without killing the cell but why cant you xray the cell or something and see if it has a mutation that way (without killing it) I mean you can xray through solid objects
    is it because there would be too much movement or something?
