We use a lot of borrowed analogies from other sciences; linguistics, computational sciences but what do we really mean, mean with information in living systems?

    $\begingroup$ Somewhere to start might be The concept of information in Biology by John Maynard Smith, including this in the opening paragraph "Developmental biology can be seen as the study of how information in the genome is translated into adult structure, and evolutionary biology of how the information came to be there in the first place" $\endgroup$ – user1136 Nov 10 '18 at 13:46

    $\begingroup$ bioinformatics can be a research topic. $\endgroup$ – aliential Nov 10 '18 at 16:14
  • $\begingroup$ The word "information" is not borrowed from any other science, it is borrowed from the English language. The genetic code, for example, was deciphered before most University Computing Science departments were established. This question is both basic and wide. I would start by reading about the genetic code, which is used to encode a certain subset of genetic information. If your background is such that you can't understand the Wikipedia entry or other web accounts, you need to buy and read a molecular biology text. $\endgroup$ – David Nov 10 '18 at 20:59
