It’s 2013! Almost 70 years have passed since the first electronic general purpose computer-ENIAC was made. But the last decade has witnessed a tremendous advancement of personal computing as well as multipurpose super computers.
We have most advanced hardwares and accessories for our pc and of course memory devices are now at terabyte range. Think about Floppy discs-the ancestor of cd’s and dvd’s which could hold at most about 1.4 mb. We can’t even imagine using them again.
But we are humans and our needs and time, both are non-stopping and continuous. So all these advanced storage devices are becoming inadequate for us.The scientists are working hard to establish more and more resources for the advanced computing as per our requirements and the most eagerly awaited research is DNA-Computing!
Yes it’s time for DNA chips instead of the existing silicon chips. Let me make you clear with the scope of this research. George Church and Sr i Kosur i of Harvard’s Wyss Institute were able to store 5.4 Petabits of data; that means almost 700 Tb in a single gram of DNA. Isn’t it mind-blowing? Just like the magnetic or silicon semiconductor storage devises DNA can also used for the same purpose in a much higher level, they says. They synthesized DNA strands each of which can store 96bit. The bases (TGAC) were coded with binary values (T and G = 1, A and C=0).
The data stored in this manner can be read by sequencing the DNA. Also there is a 19 bit address block at the beginning of each strand thus aiding the sequencing process.
Researches in DNA computing were active at different parts of the world over last two decades going parallel with The Human Genome Project. The main reason for this concept of DNA based storage devices are their high data density; we can store one bit per base, and a base just has a size of a few atoms and they are highly stable.
The DNA can be easily stored ordinary room conditions for hundreds or even thousands of years. With the help of most advanced technologies such as microfluidics and labs-on-a-chip ,the synthesizing and sequencing of DNA has become a very easy task. Hopefully this will the visions of some great scientist about biological computers come true in the near future.
Who knows if there will be time where we can humans synchronize our self with our Bio-PC which can read our thoughts and act according to our will let’s wait, Tomorrow is for DNA computers.
