![]() ![]() Barbara McClintock in studies of peculiar inheritance patterns found in the colors of Indian corn, jumping DNA refers to the idea that some stretches of DNA are unstable and “transposable,” ie., they can move around – on and between chromosomes. Nearly half of the human genome is composed of transposable elements or jumping DNA. DNA has this too, where it is called ’transposing code’: dll on Windows) code cannot use static addresses internally because the code may appear in different places in memory in different situations. ![]() A larger number of these amino acids combined are called a ‘polypeptide’ or ‘protein’, and these are chemically active in making a living being.ĭynamically linked libraries (.so under Unix. Because each digit can have 4 values instead of 2, a DNA codon has 64 possible values, compared to a binary byte which has 256.Ī typical example of a DNA codon is ‘GCC’, which encodes the amino acid Alanine. Whereas a digital byte is mostly 8 binary digits, a DNA ‘byte’ (called a ‘codon’) has three digits. Where binary encoding has 0 and 1 to work with (2 - hence the ‘bi’nary), DNA has 4 positions, T, C, G and A. The language of DNA is digital, but not binary. It is very doubtful that there is a source to this byte compilation - what you see is all you get. Depressingly enough, this is only 3.6 (update: used to be 2.8, apparently Firefox decreased in size, huh.) Mozilla browsers.ĭNA is not like C source but more like byte-compiled code for a virtual machine called ’the nucleus’. The human genome is about 3 gigabases long, which boils down to 750 megabytes. The source can be viewed via a wonderful set of perl scripts called ‘Ensembl’. Maybe we should ask the walking product of this source: Craig Venter (update: not quite true, it is mostly someone else). To see where I got all this from, head to the Bibliography (end of the page). If you spot mistakes, please contact me ( / not trying to force my view unto the DNA - each observation here is quite ‘uncramped’. Since 2001 I’ve learned a few things and I think I need to This page was started somewhere in 2001, and it may need some more updating (Update: 20 years after starting this post, I can fake it reasonably well. This is some rambling by a computer programmer about DNA. If you like this page, you’ll love the presentation. Includes slides and video and a summarizing blogpost. This page has led to a two-hour presentation called DNA: The code of Life as presented at SHA 2017. Revision made by Tomás Simões ( / Feel free to contact me if I made a mistake. This article has been revised and updated, scientifically and in terms of dead links. 12th of September 2021: I’m writing a book on DNA!
