comment Can paper/plastic currency serve as a medium for pathogens?
The same may be said for any of the pathogenic E. coli which can persist on surfaces (including plastic) for a day or two.

hehe, just listed a promoter since it's what was on my mind at the time. ;)

comment Proteins that are strongly overproduced in E. coli and S. cerevisiae?
I think this comment (with respect to E. coli) was addressed here (biology.stackexchange.com/questions/5197/…). If you're looking to maximize plasmid protein expression, then you'll want a highly active constitutive promoter (eg, CMV), and then depending on codon optimization and many other factors, you might get ~20% by weight of your protein.

comment Can a human smell through the ears?
Exactly. Just as it's impossible for eyes to perceive sound, or to smell colours.

comment What are the advantages and disadvantages of using beta-galactosidase compared to luciferase as a reporter gene?
@AlanBoyd the induction of lac is irrelevant to the discussion, but I've included it for completeness. IPTG is only required if lacZ repressor is overexpressed. For example, blue/white screening is easily achieved with X-gal alone for DH10B (TOP10) strains, Mach-T1, DH5A-T1, but not others (see page viii: tools.invitrogen.com/content/sfs/manuals/topota_man.pdf ).
