Query: Great book, bad cover.

I am in the bioinformatics business, and I loved this book. It should be possible for someone to understand this subject even if they don't have a background in the biological sciences. It is much more fun if you have such a background though.The DNA double helix on the cover is twisted the wrong way. How many other errors of fact are there in the text?
