4. Animals consume other organisms
I hope this helps someone out.
trying it now
yo its correct.

To determine which of these statements about DNA is true, we need to analyze each statement individually.
1. All animals have DNA: This statement is true. DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions used in the development and functioning of all known living organisms. Animals are a subset of living organisms, so it can be concluded that all animals have DNA.
2. DNA is too similar to use for grouping organisms: This statement is false. DNA is commonly used for grouping organisms because it carries the genetic information that determines an organism's traits, functionality, and evolutionary relationships. By comparing the DNA sequences of different organisms, scientists can identify similarities and differences, allowing them to classify and group organisms into taxonomic categories.
3. Proteins signal the cells to make DNA: This statement is false. Proteins are responsible for various functions in cells, including regulating DNA replication, transcription, and repair. However, proteins themselves do not directly signal the cells to make DNA. DNA contains the instructions for building proteins, and it is through the genetic information stored in DNA that proteins are synthesized.
4. DNA is a protein: This statement is false. DNA is not a protein; it is a nucleic acid. Proteins and DNA are two distinct types of macromolecules. Proteins are composed of amino acids, while DNA is composed of nucleotides.
Based on the analysis, the true statement about DNA is: All animals have DNA.
