How Much Information Is Actually in Your DNA?

This article delves into the question of how much information is contained within human DNA. A simple calculation suggests around 1.5GB, but this overlooks redundancy and compressibility. The author explores two definitions of information from information theory: storage space and Kolmogorov complexity, comparing their application to DNA. Ultimately, a new definition – phenotypic Kolmogorov complexity – is proposed as a better reflection of DNA's true information content, although its precise calculation remains elusive.
