DNA (deoxyribonucleic acid; deoxyribonucleic acid) encompasses all of the genetic information in the form of the individual genes. It consists of a chain of nucleotides, which are assembled in a double helix structure and form the blueprint of all life. The DNA is found in all of our cells and if their structure is disturbed, this can cause cancer and numerous other diseases. Changes to the DNA arise, for example, from mutations, but alcohol and tobacco consumption also cause damage to the DNA, which increases the risk of corresponding diseases. With the DNA, so-called hereditary diseases are also passed on for generations, which can also help in the identification of particularly vulnerable people. Overall, research into the decoding of DNA has made massive progress in the past decades and various approaches have been tried in which specific diseases are treated by targeted changes in DNA. However, from an ethical point of view, these remain highly controversial. (fp)
