     Which statement describes DNA?  a. It\'s a double helix.  b. The backbone sugar-phosphates confer polarity to the strands.  c. The strands are held together by nucleotide bases.  d. The number of T\'s = A\'s, and C\'s = G\'s.  e. All statements are true. 
  
  Solution
all the statements regarding the DNA are correct.
DNA exists as a double helical structure with the length of about 2.2 meters in which the polarity of the strands is determined by the sugar-phosphate backbone. the strands are held together by the nucleotide bases and the ratio of T\' = A\'s AND C\'s=G\'s is same.
therefore the correct and is (E). ALL STATEMENTS ARE TRUE
