what ?!?!?!?
that was a joke today i cheked my bio book and i found out for u :
(A)denine
(G)uanine
(C)ytosine
(T)hymine.
and there is one more (U)racil that isnt there in DNA but in RNA

DNA has only four bases whether it is the DNA from grass blade or an elephant. These are: adenine, guanine, cytosine, thymine.However the DNA content varies. From the mass of the DNA per nucleus calculate the number of nucleotides and from the amount of nucleotides calculate the amount of bases and from the molecular weight of each nucleotide you can calculate how many bases would be in the nucleus of a cell of an organism. All you have to do is remember Avogadro's number, molecular weight of a nucleotide and that of a base.

The human genome contains 3 billion (3 x 109) base pairs. Because of base pairing, the number of Adenine (A) bases is equal to the number of Thymidine (T) bases; just as the number of Guanine (G) bases is equal to the number of Cytidine (C) bases. However, as higher eukaryotes, humans have what is referred to as a "low G/C content", that is: in humans G+C basepairs account for about 43% of the total DNA, whereas bacterial DNA is over 50% G+C basepairs. Remember also that humans are diploid, that is: each human cell (except for sperm and eggs) contains two copies of the genome, for a grand total of 6,000,000,000 basepairs.

HI FRIEND! there r 4 types of bases in DNA:-
adenine,thymine,cytosine,guanine.
and in some cases(like RNA) thymine is replaced by uracil.

Threre are four bases Adenine(A), Guanine(T), Cytosine (C),Thymine (T) in humans,,
It can be change for different species whose life of base is not carbon

adenine ,guanine ,cytosine,thyamineare the base pairs in dna whereas in rna thyamine is replaced by uracil anether base
