dna chips

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.
