If you know the DNA sequences of alphabet letters, you can PCR probe
for common words or word fragments like "the" or "ing" and avoid
total sequencing.

A recent Genetic Engineering News says the price for synthetic DNA is
dropping from $1 per base to about $0.50 per base. That works out to
$0.25 per bit. That's about 8 orders of magnitude more expensive than
PC disk storage.
