In practical terms, a DNA computer
bears similarity to a biochemical machine in which biochemical events perform algorithms and execute programs by manipulating DNA strands in a series of carefully orchestrated biochemical processes.
Once researchers are able to design reliable DNA computers
that make a mistake only once every 10 billion times, say, then I think people will become comfortable with the idea.
For now, there are a lot of things that this DNA computer
A microlitre of solution containing the molecules could theoretically hold up to three trillion DNA computers
, the scientists claim.
First, because it's in its infancy, most existing DNA computers
consist of only synthetic, made-to-order DNA strands attached to gold plates on one end, with the other end floating freely in test tubes or petri dishes that are linked to myriad scientific devices in university labs.
Japan's major precision-instruments maker said the main feature of what it calls the ''world's first functional DNA computer
for gene analysis'' is that it reduces the time required for gene expression profiling to about six hours from three days typically taken by the conventional manual process with DNA microarrays.
In a DNA computer
, computation takes place in test tubes.
Under proposals in the Bill a DNA computer
database will be set up to help detectives track down and prosecute crooks from evidence left at crime scenes.
President Tsuyoshi Kikukawa) has announced the successful development of the world's first functional DNA computer
for gene analysis, an area with enormous projected research- and analysis-related demand.
A team of researchers has now added two new operations to DNA's biocomputing bag of tricks--tools that they will need eventually to build a DNA computer
If successful, the results will be checked against a national DNA computer
base of known offenders in the hope of providing a positive match.
