Genetically identical cells can have many variable properties. A study of correlations between cells in a lineage explains paradoxical inheritance laws, in which mother and daughter cells seem less similar than cousins. See Letter p.468

I was first introduced to RNA in 1962. As a newly minted PhD in synthetic organic chemistry I had just joined in Madison, Wisconsin a team of four postdocs charged with the challenging task of chemically synthesizing 64 ribotrinucleotides by the most modern methods (manual synthesis, of course, requiring gallons of dry pyridine every day). My advisor, Har Gobind Khorana, a man of boundless energy, vision and courage, was convinced that these RNA triplets would be essential for the elucidation of the genetic code. It was an exciting time in molecular biology as the first details of the mechanism of protein synthesis and the genetic code emerged. Then, after three years of intense work with great team spirit the code was cracked! At the end of my time in Wisconsin I had become a molecular biologist, spellbound by the genetic code and by tRNA. I would never lose interest in this molecule, and it guided my research for the next five decades.
Fast forward to the mid-nineteen-nineties, when the RNA journal was launched, the era of genome sequencing began, and I returned to studies of the genetic code. At that time we dabbled for the first time in using Archaea for our research; we discovered that tRNA-dependent asparagine (Asn) formation provides Asn-tRNA for protein synthesis, and later showed that in many organisms this process is also the required supply route for the free amino acid. Then a phone call changed my research direction for the next 15 years. Carl Woese, whose early inquiries into the genetic code and tRNA, summarized in his influential “little book” The Genetic Code, the Molecular Basis for Genetic Expression (published in 1967; now available used from Amazon as a collector's item for $604!), had made a big impression on me back then. Carl had just called. He told me that the genome sequence of the first archaeon, Methanococcus jannaschii (now renamed Methanocaldococcus jannaschii), would appear in print soon, and that the genome lacked the gene for the essential cysteinyl-tRNA synthetase. “How are you going to explain this?” he asked. Without any hesitation I replied that I would solve the riddle, totally unaware that it would take us a decade of sustained and unfamiliar work with many archaeal species to come up with the correct and exciting solution! Thus, we launched investigations with organisms whose names were hard to pronounce, even more difficult to grow, that were anaerobes, and some of them with stunning optimal growth temperatures exceeding the boiling point of water; all of this was totally unfamiliar to us. However, given our thrilling unexpected first results and considering the vast diversity of microbes that would soon be available via their genome sequences, we felt that careful analyses of these organisms for anything that diverged from the accepted view of protein synthesis and genetic coding would possibly lead to surprising new concepts. And given the vast organismal diversity out there, we wondered how many different routes (or exceptions to the currently accepted dogma) of protein synthesis, tRNA formation and the genetic code would be represented in this biological universe.

"OVER THE LAST several decades, DNA – the genetic material of life as we know it – has completed a remarkable scientific cycle. In 1953, it was a mysterious blur on an X-ray diffractogram. By the 1970s, it was possible to determine the sequence of short nucleotide chains. And now, a scientist can produce her own genetic code of choice with the click of a mouse.
