Question for biologists and uhh... people who understand computing ^_^?

Although each nucleobase does only pair with one of the other three, that does not make it a binary system - down each side of the helix you can still have one of four nucleotides, and the two which partner each other are not equivalent. But, in a way, there is a conection with computing - very simple DNA computers have been created. The main problem is that at the moment they are non-programable - a DNA computer has to be designed for a very specific problem.

The concept of DNA computing has been proposed before because it can be massively parallel (many cells working on their DNA together, you get the idea). The main idea is that through a process of selection a "correct" DNA sequence will eventually emerge over time. I'm not sure how the information is coded in order to resist mutations, but practical examples (proof of concept) have already been presented. Just like all things chemical, the process is slow and I'm not sure it is worth it unless we manage to make it run with a speed in the order of Gb/sec. From a theoretical standpoint, the resulting computer is still a Turing machine and not necessarily superior. You can get a zillion results if you try the terms "DNA computing" in your favorite search engine. I quote wikipedia below.

Tell you a joke: -Doctor! I have a serious problem, I can never remember what i just said. -When did you first notice this problem? -What problem? Bye, hope you like it. Be happy everyday. I need to go to level 3. Help me and vote for me and I will vote for you! Thanks! :-) One more joke: A guy calls his vet and says "What should I do with my cat?Vet says "What do you mean? Guy says "I had a leak in my lawnmowers gas tank and the cat drank the gas. Then the cat began to run around and around the yard, climbed a tree. then fell out of the tree stiff. Vet says "Is the cat dead? Guy replies "nope he ran out of gas.

Yes, there are some remarkable similarities between technology and biology. Some people believe that sometime in the future the two will merge. Hey, you told those jokes in the last question too, do you know any others?

Well, scientists have actually thinking about using DNA for binary data storage. But one problem is that since DNA is a biological material, it's not stable, but will degenerate over time. (This is mutations happen) Another problem is how we can transfer data into a computer readable form quickly. A third rpoblem, which I personally don't worry much about, is the fear that the DNA will start lives it's own life and take over the computer. /Edit: My point regarding intelligence is that at some point it will be a practical obstacle in research and marketing of a DNA based memory products, that people fear it will form some kind of life form. That is an overrated fear according to me. The biggest problem is chemical instability. /Edit 2: "Fat (bytes of stored energy)" That's actually funny, even though the poster might not have thought about it. FAT is, apart from a lipid substance, the name of a computer file system.

well never herd something about that. i personally think there could be no relation. the main reason being, the human has evolved over a long period of time from very small minute creture to the most intelligent species of th world. and computer understands only two things thats "0" & "1" . this is human only who made it. human only for his/her convrnience let the computer to understand two things. so i think there is very less possibility in both the above.

Computing and living have many things in common. Memory(storage) Recounting (web search),Input(food water air ),,Booting(refractory period), Fat (bytes of stored energy),Brain (cpu), Conditioned reflexes (programed)Learn (download).etc. But there is one difference which I can not explain. Humans and animals are LIVING, and computers are not.
