Pregunta 24

Which statements correctly compare the DNA of a buttercup with the DNA of a horse? Select all that apply.

  1. Each species has its own extra bases
  2. Both species use the same four basesRespuesta correcta
  3. The order of the bases differs between themRespuesta correcta
  4. The horse uses more kinds of base than the buttercup

Explicación

Living things share one chemical alphabet, so both species build DNA from the same four letters, and the difference between them lies in the sequence those letters are written in. Giving a species extra bases would mean the pairing rule changed from organism to organism, which is not what is found.
