Yes all information about DNA above is right , DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.Dna store information which is dependent on genetic code , which dependent on the genetic code. The code which define relation between the sequence of bases in DNA (or its mRNA transcript) .Every cell in the human body carries a bundle of DNA in its
nucleus — nearly 30,000 genes, and the chunk fromdna become proteins.. Each of the 46 chromosomes in a human
cell’s nucleus bears thousands of genes.
