In a polynucleotide, what hydroxyl position is linked to the 5' position of 2-deoxyribose?
  A)
  1'
  B)
  2'
  C)
  3'
  D)
  4'
  E)
  5'

Question 2

Which statement(s) is/are false relative to the secondary structure of DNA?
  A)
  DNA consists of two helical polynucleotide chains coiled around a common axis.
  B)
  The helices are left handed and the two strands run in same directions relative to their 3'and 5' ends.
  C)
  The two chains are held together by hydrogen bonds between purine and pyrimidine bases.
  D)
  The purine and pyrimidine bases lie inside the helix, in planes perpendicular to the helical axis; the deoxyribose and phosphate groups form the outside of the helix.
  E)
  There is no restriction on the sequence of bases along a polynucleotide chain. The exact sequence carries the genetic information.
