DNA

• What is the structure of DNA?

  DNA is a double helix of paired bases.
• What does DNA contain?

  DNA contains all of an organism's genetic material.
• How is DNA arranged?

  DNA is arranged into enormous coiled molecules.
• What are short sections of DNA called?

  Short sections of DNA are called genes.
• What is a nucleotide?

  A nucleotide is a building block of DNA made up of a sugar, a phosphate group, and a base.
• What is the significance of the bases in DNA?

  The bases are the only part of the nucleotide that varies.
• How many different bases does DNA have?

  DNA has four different bases.
• What are the four bases of DNA?

  The four bases of DNA are A (adenine), G (guanine), C (cytosine), and T (thymine).
• What is complementary base-pairing in DNA?

  Complementary base-pairing is when A pairs with T and C pairs with G.
• Why is complementary base-pairing important?

  It keeps the two DNA strands tightly wound together.
• What is a polymer?

  A polymer is a large, complex molecule composed of long chains of monomers.
• What are monomers?

  Monomers are small, basic molecular units.
• How is DNA classified as a polymer?

  DNA is a polymer made up of nucleotide monomers.
• What are the components of a DNA nucleotide?

  • A sugar
  • A phosphate group
  • A base (A, C, G, or T)
• What is the process of base pairing in DNA?

  • A pairs with T
  • C pairs with G
  • Forms cross links between strands
• Why is complementary base-pairing important in protein synthesis?

  • It ensures accurate transcription of genetic information
  • It maintains the structure of DNA
• What is the relationship between DNA and proteins?

  • DNA contains the instructions for protein synthesis
  • Proteins are synthesized based on the sequence of bases in DNA
• What is the significance of the double helix structure of DNA?

  • Provides stability to the molecule
  • Allows for efficient replication and transcription
