Universal Genetic Code? No!

The basic process by which proteins are made in a cell. (click for credit) The basic process by which proteins are made in a cell. (click for credit) I am still reading Shadow of Oz by Dr. Wayne Rossiter, and I definitely plan to post a review of it when I am finished. However, I wanted to write a separate blog post about one point that he makes in Chapter 6, which is entitled “Biological Evolution.” He says:

To date, the National Center for Biotechnology Information (NCBI), which houses all published DNA sequences (as well as RNA and protein sequences), currently acknowledges nineteen different coding languages for DNA…

He then references this page from the NCBI website.

This was a shock to me. As an impressionable young student at the University of Rochester, I was taught quite definitively that there is only one code for DNA, and it is universal. This, of course, is often cited as evidence for evolution. Consider, for example, this statement from The Biology Encyclopedia:....

This has been known for a long time. Different forms of ribosomal rnas in different species translate the mrnas using different amino acids.
