DNA i.e. Deoxyribonucleic acid is a long linear double helical polymer found in the nucleus of a cell and formed from nucleotides. It is associated with the transmission of genetic information.
The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The sugar present is deoxyribose. A phosphate group is attached to the sugar molecule in place of the -OH group on the 5' carbon. In DNA there are 4 bases, which are cytosine (C), thymine (T), adenine (A) and guanine (G). A DNA strand is simply a string of nucleotides joined together. The phosphate group on one nucleotide links to the 3' carbon atom on the sugar of another one
