DNA

• What should you be able to describe by the end of the video?

  The structure of DNA and other polymers
• What are proteins described as in the video?

  Naturally occurring polymers of amino acids
• In which organisms is DNA found?

  Almost all living organisms
• What is the role of DNA in living organisms?

  It encodes genetic instructions for development
• What are the monomers that make up DNA called?

  Nucleotides
• How many different nucleotide monomers are there in DNA?

  Four different nucleotide monomers
• What do scientists call the nucleotide monomers for short?

  G, A, T, and C
• What structure do the two polymer chains in DNA form?

  A double helix
• What are the two other naturally occurring polymers mentioned?

  Starch and cellulose
• What are starch and cellulose polymers of?

  Glucose
• How do the glucose molecules in starch and cellulose differ?

  They are arranged in slightly different ways
• What are the key characteristics of DNA structure?

  • Composed of two polymer chains
  • Made from nucleotide monomers
  • Forms a double helix structure
  • Contains four nucleotide types: G, A, T, C
• What are the types of naturally occurring polymers discussed?

  • Proteins (polymers of amino acids)
  • Starch (polymer of glucose)
  • Cellulose (polymer of glucose)
