HOW DID SCIENTISTS DISCOVER HUMAN DARK MATTER?
Human DNA is like a huge book containing the exact instructions for building a person. Here, spread over around three billion pages, is the complete protein code. These gene sequences dictate the makeup of a protein and have become essential to the study of dark matter in the body. That’s because, biochemically speaking, dark proteins are simple molecules – and their instructions are neatly written in the DNA. Together with an international research team, Dr Bernhard Kuester from the Technical University of Munich has read these blueprints. Using the human gene map, which lists all of the genes in the genome, the researchers were able to find out which proteins are actually built by the body. While this doesn’t necessarily tell us anything about what they do, it’s possible to compare these protein assembly instructions with the known proteome – and, therefore, get an overview of the amount of dark matter in the body.
