...four different nucleotides, rep- resented by the letters A, T, G and C. Grouped into sets of three steps, the nucleotides are called codons, which dictate, or code for, the 20 amino acids, the subunits of protein. A few codons, or code words, serve as punctuation marks, telling the cellular machinery to start or stop adding amino acids to the growing protein chain...
...error in our technique." However, news soon filtered over from the Centre de Genetique Moleculaire laboratory near Paris that scientists there were encountering the same anomaly. As the two groups report in a recent issue of the British journal Na- ture, additional experiments showed that whenever the Paramecium's cellular machinery read either of two "periods" (TAG and TAA) in the standard code, it linked the amino acid glutamine onto the protein chain rather than stopping production; it obeyed only the third word for stop, TGA. At Nagoya University in Japan, scientists have found that Mycoplasma also ignores a stop...

...There is a lot of interest in seeing him return," said Chairman of the Cellular and Developmental Biology Department Richard M. Losick. Dean of the Faculty A. Michael Spence "has been in contact with him, and in a few weeks the situation will be a lot clearer," he added...
