Read the following five statements (A to E) about nucleic acids and select the option with all correct statements: (A) DNA is a long polymer of deoxyribonucleotides. (B) The two chains of DNA have anti-parallel polarity. (C) The backbone in a polynucleotide chain is formed due to nitrogenous bases and phosphates. (D) DNA acts as the genetic material in most of the organisms. (E) Uracil is present in RNA at the place of cytosine.

The salient feature of DNA are - (i) It is made of two polynucleotide chain (ii) Back bone is constituted by sugar and nitrogen base (iii) Two chain hacve parallel polarity (iv) Bases in two strands are paired through H-bonds (v) The two chain are coiled in a left handed fashion
