What is DNA ?
DNA stands for Deoxyribonucleic Acid
All organisms on this planet are made of the same type of genetic element.
DNA carries the genetic information of a cell.
Within the cells of any organism is a substance called DNA which is a double stranded helix of
nucleotides.
Each strand is a series of
4 different nucleotides
Adenine (A)
Guanine (G)
Thymine (T)
Cytosine ©
DNA Structure :-
The key thing to note about the structure of
DNA is it’s inherent complementarity
A binds with T and G binds with C
One strand is therefore the “mirror image of another”
Complement of AGGCT is TCCGA
Complement of TAGGA is ATCCT
Complement of GATTACCA is CTAATGGT
Interesting Facts :
DNA molecule is 1.7 meters long
Stretch out all the DNA in your cells and you can reach the moon 6000 times!
DNA Computing :-
Around 1950 first idea (Precursor Feynman)
First important experiment 1994: Leonard Adleman
Molecular level (just greater than 10-9 meter)
In only 5 grams of DNA we get around 1021 bases !
Each DNA strand represents a processor !
