News: Two simultaneous codes in DNA

Most “news” items get posted on our Facebook page, but this one is so significant that we are posting it here as well: a new study reports that DNA contains two completely different codes simultaneously. The one we’ve know about for years codes for proteins, but another one simultaneously gives directions to the cell about turning processes on and off. This is sort of like writing a novel which has another novel embedded in it if you take only every first letter of the words.

We already new that there is “frame shift” information coded in DNA as well. This is like having a message all of three-letter words, and then dropping the first letter of the message, and interpreting all the remaining letters as three-letter words, and getting a fully intelligible message from that string as well.

Frankly, it is pretty spooky how much information is packed into DNA.
