Qustions I can’t seem to find answers to

What is it with genetic information that is so scary. I honestly do not understand this.

The more we learn about the human genome the more we understand how little it by itself, determines. Sure, it is our genetic framework or DNA-recipe-book or whatever other analogy you want to use. But, for almost everyone of us, our DNA sequence itself does not mean much in terms of  personal or professional opportunities or even health. DNA-information is pretty useless without context basically.

Still you apparently need laws and regulations and ethical boards and counselors to protect your genetic information. Not only from the public, but sometimes even from yourself.

Your lifestyle and health (and that of your family), your friends, your living environment – those are things that really, really matters – the true life-determinators or the context if you will. Which by the way, is useful information (that can be misused or exploited) also in the absence of knowledge of your DNA-sequence.

This information however, most people are allowed to  put on the internet for everyone to see. And they do so gladly.

This is puzzling to me.

Hammering nails in the “junk-DNA” coffin

Enough talk (see this previous post and links within), on to the peer-reviewed science. Below you will find a list of references that I hope will contribute to the fall of the term “junk-DNA“, – some of it may (currently) lack a known function, but it is not junk !!!

Disclaimer: This is a list of useful references when arguing against the common overestimation of the amount of “junk”-DNA. By listing these I am not claiming anything beyond what I have already posted on this blog or in a comment somewhere. Also and importantly, I have not myself  had the time to review these articles as thoroughly as I would have wanted to, – some have been read carefully, others lightly and yet others just skimmed through. Thus, you are more than welcome to comment on these references if you have opinions on any of them, or find them unsuited for this list.

The list will be continuously expanded, and if you have references you would like to add, please notify me with a comment to the post.

The references are unsorted. Feel free to copy, rearrange and use as desired…
