Molecular "Intelligence"

The findings of Avery et al. should have clearly demonstrated the role of DNA as the master molecule of the cell.  However, since the protein "alphabet" is composed of 20 naturally occurring amino acids, vs. the four nucleotide bases of DNA, it was assumed that DNA could not in any way give rise to the wide variety of protein forms which occurs in cells.

It would take the better part of a decade for scientists to realize the potential and power of what was assumed to be a limited DNA code.
