السؤال 19

Which statements about how DNA stores genetic information are true? Select all that apply.

  1. The order of the bases carries the informationالإجابة الصحيحة
  2. The total number of bases carries the information
  3. The width of the twist carries the information
  4. Changing the order of the bases changes the instructionالإجابة الصحيحة

الشرح

Information in DNA is written as a sequence, so both the arrangement of the bases and any change to that arrangement matter. A count of bases carries no message, since two molecules with the same total can spell different instructions, and the twist has the same width in every DNA molecule.
