* DNA: DNA is the genetic material that carries the instructions for building and maintaining an organism.
* Ribosomes: Ribosomes are essential for protein synthesis, which is a crucial process for all living organisms.
Only cells contain both DNA and ribosomes.
While viruses contain their own genetic material (DNA or RNA), they lack ribosomes and rely on the host cell's ribosomes to produce their proteins.
