I find _lowercase_ acgt much easier to read than ACGT; hence, I prefer the
GenBank database entries over their EMBL equivalents.
Perhaps authors should use lowercase letters in their sequence figures to
improve readability. (I think that within a year or two sequence figures
will largely disappear, anyway, to be replaced by the accession number and
a map of the sequenced region.)
