The cell that can read all the DNA is called the "universal cell" or "universal genome cell." It refers to a hypothetical cell that has the ability to read and interpret the entire DNA sequence of any organism. This concept is based on the idea that there could be a universal mechanism or machinery within a cell that can recognize and process genetic information from diverse sources. However, it's important to note that such a cell does not currently exist in nature, and the understanding and interpretation of DNA sequences are carried out by various specialized cells and molecular mechanisms in different organisms.
