Advantages Performs millions of operations at same time
Good for parallel computing
Ability to use large amounts of working memory 1 gram of DNA can hold 1 x 1014MB of data
Or 145 trillion CDs
1 CD is 800 MB

Advantages Cheaper
Lightweight
1 lb of DNA has more computing power than allcomputers ever made
Low power used to keep in original state
Has ability to solve hardest problems in a matter of
weeks

Ethics Terrorism and Government Control
Ability to release a virus to computers inside bodies
If nanobots fail inside of body, it could destroy a personsorgans that rely upon the bot
Overpopulation
With this technology people will live longer creating a
higher demand on resources

Ethics Creation of superior race (cyborg)
Ability to use biocomputers to enhance certain abilities
Intelligence
Physical abilities
Age
These people will outperform the have nots who cannotpurchase the technology
Can be used like steroids but without the side effects

Ethics Computers taking over
Biocomputers will eventually have the capability to solveproblems on their own without human intervention
This could mean a takeover by a Terminator typecreation
Would you put your life in the hands of a computer?
Computers today are not trustworthy at all times Doctor malpractice

Disadvantages Molecular operations are not perfect
DNA computing involves a relatively large amount of
error As size of problem grows, probability of receiving
incorrect answer eventually becomes greater thanprobability of receiving correct answer.
Sometimes there are errors in the pairing of DNAstrands
Simple problems solved faster on electronic computers

Disadvantages Human assistance is required
Time consuming lab procedures
No universal method of data representation
DNA has a half-life Solutions could dissolve away before end result is found
Information can be untransmittable
Current DNA algorithms compute successfully w/opassing any information from one processor to the nextin a multiprocessor connection bus.

Medical Applications In 2004, a group in Israel claimed to have created a
DNA automaton that can diagnose symptoms ofcancer and administer a therapy
In prostate cancer, and some others, diagnosis is based onmolecular signatures
It senses messenger RNA and can detect theabnormal mRNAs produced by genes involved incertain types of lung and prostate cancer.
An anticancer drug is released if an abnormal mRNAis found It is also made of DNA Tumor related gene suppressed

Medical Applications DNA computers known as computational genes
would be integrated into the genetic materialalready in the patients cells
Computational genes are similar to ordinary geneDNA markers They will be programmed to react to a certain input with
a certain output Replacement of coding for protein structure.
Designed a computational DNA molecule thatwould answer 5 yes or no questions
Questions used to establish the typical markers ofwhether or not prostate cancer was present

Medical Applications If 5 yes answers were received, then there would be a
release of the drug. The researchers successfully applied this to a test system
that recreates the typical molecular signatures ofprostate cancer in vitro similar treatment on a test tube model of small cell lung
cancer.
This is what researchers hope is the beginning of thefuture for smart drugs Roam the body by fixing disease on the spot It would sense a change in the environment and respond by
releasing biological molecules

Medical ApplicationsWest Nile
Could be used to distinguish between the various viralstrains
Diabetes
Could monitor blood sugar levels and dispense insulin
when needed.

Medical Applications May be several decades before such a system is
operating inside the human body will become a reality
Process of introducing genetic material into a personwould need to be considered carefully. Bodies reaction may not be easily predicted

Computational Gene Challenges Delivery of the DNA into cells and incorporation into
the patients' own DNA.
Keeping them from being treated by the immunesystem as foreign invaders.
