DNA structure

• What is the structure of DNA?

  DNA is a double helix
• What are complementary strands in DNA?

  Strands that pair specific bases together
• What is DNA's role in cells?

  DNA is genetic material
• Where is DNA contained in a cell?

  In chromosomes in the nucleus
• What is DNA made of?

  Two strands of nucleotides
• What is a nucleotide composed of?

  Phosphate group, sugar, and base
• How many different bases are in DNA?

  Four different bases
• What are the four bases in DNA?

  A, T, C, and G
• What does it mean that DNA is a polymer?

  It is made up of repeating units
• What does it mean for DNA strands to be complementary?

  Specific bases pair with each other
• Which bases pair together in DNA?

  C pairs with G, A pairs with T
• If given a nucleotide sequence of one strand, what can you determine about the opposite strand?

  You can deduce the complementary nucleotides
• What are the key components of a nucleotide?

  • Phosphate group
  • Sugar molecule
  • Base (A, T, C, or G)
• What is the significance of complementary base pairing in DNA?

  • Ensures accurate DNA replication
  • Maintains genetic information integrity
  • Facilitates protein synthesis
• What is the structure of a DNA double helix?

  • Two strands twisted around each other
  • Strands made of nucleotides
  • Complementary base pairing between strands
