Junk & Jonathan: Part 12—Chapter 9

 
This is part 12 of my review of The Myth of Junk DNA. For a list of other postings on this topic see the links in Genomes & Junk DNA in the "theme box" below or in the sidebar under "Themes."


The title of Chapter 9 is "Summary of the Case for Functionality in Junk DNA." It is Wells' attempt to summarize the "evidence" he has presented so far.

Wells tells us that the "evidence" falls into two broad categories: (1) evidence that putative junk is probably functional, and (2) evidence that small specific bits of the genome are functional.

Within the first category there are two subdivisions: (1a) evidence that most of the genome is transcribed, and (1b) genome comparisons. Let's look at these two subcategories.
