For each of the following false statements, change the statement to make it true. Archaea are ancient bacteria that are the ancestors of modern bacteria. Bacteria differ from eukaryotes in having no nucleus, mitochondria, chloroplasts, or ribosomes. Instead of a cell wall, eukaryotic cells have an extracellular matrix for structural support. All the ribosomes found in a typical human muscle cell are identical. DNA is found only in the nucleus of a cell. Because bacterial cells have no organelles, they cannot carry out either ATP synthesis or photosynthesis. Even the simplest types of infectious agents must have DNA, RNA, and protein.
