Which of these statements about DNA is true? (1 point) Responses DNA is a protein. DNA is a protein. Proteins signal the cells to make DNA. Proteins signal the cells to make DNA. DNA is too similar to use for grouping organisms. DNA is too similar to use for grouping organisms. All animals have DNA.

Answer 1

The true statement among the options provided is: All animals have DNA.

DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions used in growth, development, functioning, and reproduction of all known living organisms, including animals. The other statements are incorrect: DNA is not a protein, proteins do not signal the cells to make DNA, and while DNA sequences can be similar among closely related organisms, they can also be quite different and are used for grouping organisms in phylogenetics.
