On Asimov Press, Dynomight asks how information there is in DNA.
How should we define the “information content” of DNA? I propose a definition I call the “phenotypic Kolmogorov complexity”. Roughly speaking, this is how short you could make DNA and still get a “human” […] So what would this number be? My guess is that you could reduce the amount of DNA [in the human genome] by at least 75 percent, but not by more than 98 percent, meaning the information content is [60 MB to 750 MB].
I agree that this is a reasonable definition and estimate. The biggest unknown is what proportion of the human genome is junk DNA, even though Dynomight avoids using that term.
