DNA

  • a long chain polymer of nucleotide monomers
  • this polymer is called a polynucleotide
  • DNA is formed by two polynucleotides joining together
  • hydrogen bonds between the bases

Hydrogen Bonding And Base Pairing

  • the two DNA strands run parallel to each other and the space between them is taken up by the nitrogenous bases projecting inwards
  • where a pyramine appears on one side, a purine is on the other
  • where the purine is adenine, the pyramine is always thymine
  • where the purine is guanine, the pyramine is always cytosine
  • as the strands…
