DNA Structure

• What is the structure of DNA primarily composed of?

  Two strands forming a double helix
• What is meant by complementary strands in DNA?

  Same bases pair on opposite strands
• What is DNA classified as?

  Genetic material
• Where is DNA contained within a cell?

  In chromosomes in the nucleus
• What are the building blocks of DNA called?

  Nucleotides
• What are the three main parts of a nucleotide?

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

  Four
• What are the four bases in DNA?

  A, C, G, and T
• What remains unchanged in the structure of DNA nucleotides?

  Phosphate group and sugar molecule
• How do the bases pair in DNA strands?

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

  The nucleotides on the opposite strand
• What is the significance of complementary strands in DNA structure?

  • Ensures accurate base pairing
  • Facilitates DNA replication
  • Allows for genetic information transfer
• What is the process of DNA polymerization?

  1. Nucleotides are linked together
  2. Forms a long DNA strand
  3. Strands wind into a double helix
• What is the role of DNA in protein synthesis?

  • Contains instructions for protein assembly
  • Guides the sequence of amino acids
  • Involves transcription and translation processes
