  • The two strands of DNA are held together by what?
    The two strands of DNA are held together by hydrogen bonds between complementary bases.
  • The twisted ladder shape of DNA is called a what?
    The twisted ladder shape of DNA is called a double helix.
  • DNA is made of repeating subunits called what?
    DNA is made of repeating subunits called nucleotides.
  • A nucleotide of DNA may contain which components?
    A nucleotide of DNA may contain a phosphate group, a deoxyribose sugar, and a nitrogenous base.
  • Which base is not found in DNA?
    Uracil is not found in DNA.
  • Which DNA base pairing is correct?
    Adenine pairs with thymine, and cytosine pairs with guanine.
  • Why is DNA more stable than RNA?
    DNA is more stable than RNA because its sugar, deoxyribose, lacks a hydroxyl group at the 2' carbon, making it less reactive.
