====== DNA SEQUENCE ======

         * एक गुण सूत्र ऐसे दो सूत्रों से बनता है 
           * एक सूत्र 5' - 3' दिशा में जाता है 
           * दूसरा सूत्र 3'-5' दिशा में जाता है 
           * दोनों सूत्र एक दूसरे से hydrogen bond से जुड़े रहते हैं 
         * double helix 
           * each helix has 10 pairs
           * packing of DNA helix
       * गुणसूत्र के छोर ( ends ) 
         * ऊपरी छोर 
           * 5th carbon atom of sugar is not linked with any other 
             * terminates in phosphate 
               * called as 5'P terminus 
         * निम्न छोर 
           * 3rd carbon atom is not linked to other nucleotide 
             * bears hydroxyl group 
               * called 3' end or 3' OH terminus
