DNA

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

  The structure of DNA and other polymers found in living organisms
• What are proteins described as in the context of polymers?

  Proteins are naturally occurring polymers of amino acids
• In which types of organisms is DNA found?


  Almost all living organisms including animals, plants, fungi, bacteria, and viruses
• What is a notable exception regarding DNA in viruses?

  Some viruses do not contain DNA but have a related molecule instead
• What does DNA encode for living organisms?

  Genetic instructions needed for development and function
• What are the monomers that make up DNA called?

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

  Four different nucleotide monomers
• What are the short names scientists use for the nucleotide monomers in DNA?

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

  A double helix
• What term should you use in your exam to describe the structure of DNA?

  Double helix
• What are the other naturally occurring polymers mentioned in the video?

  • Proteins (polymers of amino acids)
  • Starch (polymer of glucose)
  • Cellulose (polymer of glucose)
• How are the glucose molecules in starch and cellulose different?

  The glucose molecules are arranged in slightly different ways
• Where can you find more questions on DNA and other polymers?
