Data in DNA
-
Well, scientists announced they can now store data in DNA. One has to wonder if that's how life here got started - "Coded" DNA left on the surface of the petri dish that we call "Earth".

This is actually, very interesting to me. I will fight the urge to post back funny/not funny comments. This also sounds a bit scary. :~

They would probably use 'Junk DNA' as storage space and then it will probably quickly be seen that some sequences were not evolutionary rubble at all. Hopefully such a massive and undeliberate mutation will not be able to survive.

Bah! I've been doing this since I was about 13.

Well... if we follow the timeline of bits available backwards from 64 to 32 to 16 to 8... so on, so forth... it was truly binary programming then? Well... that makes sense... 1 and 0... in a phallic sort of way...
DNA uses triplets of four possible nucleotides (Adenosine, Cytosine, Guanine, and Thymine) to encode 21 different amino acids. This implies a 6-bit system with some redundancy. Perhaps DEC's early PDP machines (12-bit PDP-5 & -8, 18-bit PDP-1, 36-bit PDP-7 & -10) were on to something!
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

Then it's only a matter of time before the NSA puts spyware into our DNA!!

That's very insensitive to the massive and undeliberate mutations out here. Very insensitive, indeed. :((

Best and most true answer of all. I guess you are officially a "Scientist". Probably of the mad variety. :D And, by mad, I mean completely lunar.

At one recent event, a 12 second clip was encoded and the resultant DNA put into a soap suspension. Audience members were then asked to blow bubbles using the soap so that each of them could leave carrying the music on their skin. Gee we humans can be so incredibly self-indulgent. Musical DNA soap, $300,000 lab-'grown' beef burgers, tourist trips into space. ;sigh; http://www.popsci.com.au/science/band-will-release-album-in-dna,398158[^] http://thecreatorsproject.vice.com/blog/music-of-the-spheres[^] As for the proposition you consider - here's some reading if you're up for it.

"When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down 'happy'. They told me I didn't understand the assignment, and I told them they didn't understand life." - John Lennon

DNA uses triplets of four possible nucleotides (Adenosine, Cytosine, Guanine, and Thymine) to encode 21 different amino acids. This implies a 6-bit system with some redundancy. Perhaps DEC's early PDP machines (12-bit PDP-5 & -8, 18-bit PDP-1, 36-bit PDP-7 & -10) were on to something!

I think it may be a trinary (+0-) system with significant null states.
The difficult may take time, the impossible a little longer.

A DNA codon consists of 3 base-4 digits (each digit may be one of A, C, G, or T), giving a total of 4^3 or 64 possible values. I fail to see how you could represent 64 states in trinary without some "forbidden" values.

You are correct. That's what I get for trying to do complex math in the wee hours of the morning. Just as an aside, what would our computer math be like if the early computer developers had used three states for a bit instead of two?

It depends on which ternary notation you mean. If we used "standard" ternary notation (0, 1, 2), the increased complexity of the circuitry is very likely to make it uneconomical compared with binary notation. Calculation using balanced ternary (-1, 0, 1) has some advantages, but I question whether the increased complexity of the circuitry would make it more viable than binary. I note that only two models of ternary-based computers were built, both in the Soviet Union. Neither was a wild success. http://en.wikipedia.org/wiki/Setun[^] http://www.computer-museum.ru/english/setun.htm[^] If, however, we were to use ternary logic as representing "no", "maybe", and "yes" (i.e. one value implies that the datum is uncertain), we might have something new. I don't know of attempts to program "fuzzy logic" in ternary, but would be interested in any examples...

DNA uses triplets of four possible nucleotides (Adenosine, Cytosine, Guanine, and Thymine) to encode 21 different amino acids. However, the encoding has no frame of reference. That is, encoding can begin again shifted by 1 or 2 nucleotides. Additionally, the encoding is also represented on the reverse complement making a total of 6 frames of reference, and any or all may be valid. In a programmers world, this is like encoding a second (or third) program by shifting the starting op-code by 1 byte and getting another valid program. Even weirder, imagine shifting the start by 2 bytes, then taking the one's complement of the program and reversing the bit-order to get another valid program. We enforce encoding to have a definitive start, but DNA has no such restriction and allows for a much higher information content.
