"When it comes to storing massive amounts of information, nothing comes close to the efficiency of DNA. A single strand of DNA is thousands of times thinner than a strand of human hair. One pinhead of DNA could hold enough information to fill a stack of books stretching from the earth to the moon 500 times.
"Although DNA is wound into tight coils, your cells can quickly access, copy, and translate the information stored in DNA. DNA even has a built-in proofreader and spell-checker that ensure precise copying. Only about one mistake slips through for every 10 billion nucleotides that are copied."
