lConsider the problem of forming a simple specified protein:
l100 linked amino acids
lUsing the 20 standard amino acids
lImagine that all the nitrogen in the universe is tied up in 100-link amino
acid chains, each of which trade partners as
fast as the amino acid can move a short distance
at standard temperature &
pressure.
lThere is only one chance in 1028 that the specified protein would be
formed in the entire history of the universe!
