Answer 1

The true statement about DNA from the options provided is:

All animals have DNA.

The other statements are false. Specifically:

• DNA is not a protein; DNA (deoxyribonucleic acid) is a nucleic acid.
• DNA is sufficiently diverse to be used for grouping organisms; it is not too similar.
• Proteins do not signal cells to make DNA; rather, DNA is involved in the coding and synthesis of proteins through processes like transcription and translation.
