This person is _soliciting_ email questions in a range of fields. That
implies expertise, coupled with some ability to know what one knows
and what one does not. And now we see that even an attempt to correct
a reply is incorrect. Beware!

no, you mean prototroph, but even that is questionable. Wild types may

and also the first one. Otherwise you wouldn't get the four groups you
promised us.
