DNA is a Nucleic Acid
  • Nucleic acids are information storage molecules.
  • They provide the directions for building proteins.

Transcription
Translation
4
  • Two strands of DNA join together to form a double
    helix.

5
  • Nucleotide monomers are linked into long chains.
  • These chains are called polynucleotides, or DNA
    strands.
  • A sugar-phosphate backbone joins them together.

6
  • Nucleic acids are polymers of nucleotides.

  • Two strands of DNA join together to form a double
    helix.
  • Base pairing
  • A-T
  • G-C
